A cubic centimeter of water in the metric system is 1 milliliter, weighs 1 gram and 1 joule of energy raises the temperature of this water with 1 degree Celsius so everything is nicely connected.
@@jannowak2352 Small correction: one calorie (former unit of energy) raises a gram of water by 1°C or 4.18 Joules. The metric system is awesome but nature is tricky. The Joule is defined as being the work of a motive force of one newton whose point of application moves one meter in the direction of the force
@@kolimarvelcor3104 yeah, almost. You mix Joule and Calorie and break 'unity', s'all good. my remembrance [ from the 80's ] is the Specific Heat Capacity is [ roughly ] 4,200 joules/liter/degree C. that makes exactly 1 Calorie. [ 4,184 joules for accuracy Google'd ]
I am an engineer in the US. The companies I have been working at made the transition to metric around 30 years ago. I think we should start moving the community over to metric by adding the equivalent metric units in signage and state regulated packaging (I think most nutrition labels have started to list sizes in grams, which is a start.). It’s just a matter of practice to get an intuitive feel for metric sizes vs. imperial, so let’s get started already.
Deny the future the sheer joy of working out if a thread is BSW, ME, BA, NPT, BSP, JIS, SAE, and revealing the magical TPI. Shame on you. The whole thread gauge industry would collapse, there would be moral panic, dogs and cats living together, the whole book of revelations thing. Any nation capable of grasping hundreds of cartridge sizes and types and never ever loading a .45 with 9mm, is ideally set to cope with the continuing 'simplicity' of imperial fasteners. Not to mention the improved simplicity, of course, of inventing its own standards to protect its own industry and not have to deal with the evil British way of measurement.
I think the dual messaging is a fantastic idea. Even road signs... 5 miles (8km). People don't want to convert to metric because they don't know it. It may take a generation, but the longer term benefit is worth it.
@@_Dei_ You are correct, I was born when South Africa changed to metric. Well at 62 I still get to work with imperial measurements. Machines were made to last before 1960.😂. To name one wood sizes is still in inch, everyone know what a 2x3 is but not what a 48x 70 is, by the way it is the same piece of construction lumber.
@@henningventer2917True. But when you use imperial you also have subunits, like 2/5 etc. inches and so on. That is soooo complicated. Pipes sizes are many times still in inches even in Europe, for now. One has to completely quit the mixture at some point.
@@ContraVsGigi yes you are correct, like I said monny is holding us back. Take any city in the world, how many miles/km mainline piping is tbere in it? Now start to replace it with metric sized piping, remember you need atleset 1 spool piece with metric and imperial flanges to connect an new metric section.
Here is a tip for you how to get it. Do not compare imperial and metric. When you decide to use metric for a project just use a ruler, measuring tape in metric and skip the conversion in your head. You do not have to have a feel for how much is a meter like you would have it with say a yard. The biggest advantage is. You can throw the calculator away. 1 kilometer=1000 meters (Kilo=1000 used for making big numbers smaller) 1 meter=1000 millimeters. (Mille=1000 used for making small numbers big) 1 meter=100 centimeters. (Cent = 100) 1 meter=10 decimeters. (Deci=10) ...and that's how metric works. Easy, isn't it? Now you can say without calculating it what half a meter would be in millimeters or centimeters, can't you? I guess dividing by two isn't as hard as fractions of 7/8 of an inch or something similar! Five tomatoes and such bs.
"You do not have to have a feel for how much is a meter like you would have it with say a yard." given how much your feel for a yard changes while growing up and all that, i'd argue that's rather fast to learn though. but then again when you decide to use any measurements for a project, you should be yknow *measuring* them anyway, so why not do it right :P btw metric doesn't even make much sense when it's used, eg 2-by-4s are neither 2 nor 4 inches long so yeah i'd rather get a 5x10cm plank to size, than an "not 5,08 by not 10.16 cm" one with a fancy name :P *and* you don't have to figure out if your not-2-by-4-in sized pillar still fits in the "13438/16ths of an inch minus 5/8th of a pound" hole if you're already using decimal numbers like you wanna do your math efficiently instead of in "slices of an apple" like 2nd grade :P
@@nonchipThe imperial subunitary measures are a complete alien mistery for one used to metric. How on Earth can one torture himself/herself calculating things like 5/7 + 12/19 or so? :))
I was brought up using imperial measurements until I was 14 and then we changed to metric. Soooo as someone who knows both, I can tell you that metric is far easier to use and is more accurate
Metric is definitely easier and better, but never say it's more accurate. As they say in the video, imperial units or actually US Customary units are defined in metric, so there is absolutely no accuracy to be gained, both are equally accurate.
@@shreddiest that is a false argument. You can always divide into something smaller. A twip (yes I know - nobody ever uses it - but it exists) is 1/1440 of an inch or about .01764 of a mm. Which again is about 17.64 μm . You can be as accurate as you want with both systems. I think maybe the argument you are trying to make is that the common denominations of the SI-system lends themselves to more accurate measurements. That is an argument that may have some merits.
@@shreddiest Any proponent of customary will trot out the argument that Fahrenheit is the more precise unit than Celsuis. You can use the necessary number of decimals in any system to achieve the necessary precision. Though it's definitely easier if you have a system that uses consistent steps of 10 or 1000 between units.
I worked at a company (Australia) where we supplied Australia, New Zealand, some parts of Asia and America with very high end customised doors. When the Americans were getting started they actually came over to Australia to understand the manufacturing and assembly process so they would know how to install and do repairs. As we needed all dimensions supplied to us in metric they purchase a heap of measuring tapes etc while they were here. They said that it was too hard to find anything with the metric system on it in America. I was dumbfounded.
You didn’t say when that was, but it certainly isn’t true now. If you just go in your neighborhood hardware store, they may not have a Metric tape, but you can shop online and find several easily.
.. basically just shift the decimal point the right direction.... Although I don´t understand .. but there are people finding "divide by 10" similar difficult than "divide by 9" .. but they find it easy to shift the decimal point.
The rest of the world has universal healthcare and sensible gun control legislation as well, but try telling Americans to adopt either of those as well.
There is a straightforward answer to the question "why". You only have to see the videos where random people are asked simple questions like "what is 3x3x3" or "can you show a single country on the map". After watching them the answer is obvious.
Come on, not all Americans are stRupid. I know a few very smart ones. But this change has to be pushed and enforced. They did try changing a few decades ago, in the 60s or the 70s I think, but it was only partial and optional. That does not work.
@@ContraVsGigi Of course not all of them are that stupid, but in a normal European country you cannot find people who are so silly as those shown in several videos.
@@ContraVsGigi Partial could work, but optional definitely not. Like... units could be replaced 1 by 1 instead of all of them at the same time. That would be likely to meet far less resistance.
@@ContraVsGigi You don't have to push the changes to the general population. Just start teaching metric only in schools. Making daily measurement changes may have catastrophic consequences. For example changing the speedometer and speed limit units may cause issues. However that would indeed be the fastest method. You guys already use metric units in many places and slowly you guys are starting to use metric more and more so Im sure over time you'll switch over completely and measurement of length will be the last one to go. For example here in India we use metric for everything, literally everything even length. However, we still use imperial colloquially for our height. Officially we use cms for height measurement but if someone in the street asks us how tall we are, more often than not they expect feets and inches. This is kinda weird when we think about it but we're just used to it.
From an european point of view, this neolithic imperial system still lives because of US arrogance : After WW2, USA felt so powerful that they thought they could define all world rules (and nature laws, since metric system is based on natural physical constant things) ... Only americans still ask themself such a question. Rest of the world has a metric answer since a century. Please consider changing to Celsius temperature also. If you need some motivation to change, just think about it : whereas USA did lead the last century tech race, i don't know (or never heard of) any american mathematician... wtf ?
The guy at the beginning of the video is Wernher von Braun, a German Nazi who built the V2 rocket for Hitler (using the metric system of course) and later was forced to work for the US to extend his V2 to a rocket that can fly to the moon. Just for reference, since nobody seems to understand the cynicism in that part of the video.
The first time I watched that video, the unexpected joke about 9, "nein, nein, nein", LMFAO. Edit to add: I knew about von Braun, I speak a bit of German, I was/am always interested in History, born and raised using metric system.
I was in elementary school back in the early 70s when the government was working up a plan to switch the US over to the metric system. It was a failure, but I really wish they'd stuck with it. As young as I was I would have learned it and been comfortable with it like the rest of the world.
It wasn't a failure. You have Ronald Reagan to thank for that. Just him screwing over the USA once more. His reason for it was that he thought it would be to expensive. Yep, the guy that had no problem funding death squads or making backroom deals with terrorists and hostage takers couldn't even understand how being one of only a fer few countries left not using it would be detrimental for the USA.
Simple conversions to keep in mind: a cube of 1 meter size, is 1000L 1m3 full of water , has a mass near 1 ton , which means 1000 kg so 1L of water is very close to 1kg when you have this in mind, you can think very quickly for a lot of day-to-day things
@@danngehdochzunetto I totally agree, and I think that the quickest maths are done, the most effective mind, the most efficient thoughts are set up (Sorry for my english 🇨🇵)
Im from Australia and we converted to Metric in the mid 70's. The conversions are just way more simplified with Metric. But we still use certain forms of imperial measurements such as inches and feet when measuring ones height.
The most important thing is that its based on 10 and so you can easily calculate with it without having to know all those crazy number. Like how many inches has a mile ? In metric its all easy, you just need to push the decimal comma. Just forget about the conversion, and all those crazy numbers at the end of the video. That is mostly just confusing, but the 10 base is the real important thing. While imperial, i think length is based on 12 but your numbers for fluids are even based on 16, so its all a total mess.
it almost sounds like measuring things (in a modern age where you do engineering, computers and high precision things) in feet, hands, toes and potatoes, oh and stones, isn't really a smart idea? Just a thought....
Just yesterday, I watched a video where "acres" were mentioned, so I looked it up: 1 acre is the area of 1 chain X 1 furlong, 1 furlong is 10 chains, 1 chain is 66 feet (calculate yourself, how many square feet or yards that is). 640 acres make a square mile. 1 acre is also roughly 0.4 hectare. What is a hectare? 10,000m² or 100m X 100m. 100 hectare = 1km² I wonder if you can spot the difference in simplicity.
@@ContraVsGigiHa ha! People (US-Americans and elderly British) tend to view the imperial/US-customary system as more intuitive, because they grew up with it, which is only natural. There are also legacy units still lingering around all over the world. I mean: Everywhere, we still use inches for tires, dpi for print qualities, calories to measure the energy value of food etc. It is obvious that the US won't ever switch from one day to the other to metric. The financial cost would be just too high and, although unnecessarily complicated and cumbersome, it somehow works. However, it would make sense to start to always display both units in equal size and to teach predominantly metric in schools.
@@mina_en_suiza Yes, of course that is the process. People need to understand it first and get used to it. After a while you just makes things with yhe metric label and slowly you start replacing odd sizes with rounded numbered ones. It will work and does not need to be done over night.
in metric you just have to move the dot to convert from kilometer to millimeters i'm nearly 2 meters high which is 200 cm or 0.2 decameter or 0.02 hectometers or 0.002 kilometers or 2000 millimeters my volume is about 1 squarre meter X my height so my volume is 2 cubic meters which represents 2 tons of water (i'm not 2 tons but i need the same volum to fit in the volum)...size volum weight etc...without any complex calculations metric system is easy amazingly easy i can convert my size into light-years if i want (a light-year is about 10000 billions of kms so i'm one 50 millions of billionth of a light-year)
You are definitely not 2 tonnes. Although if you were, for example, 85kg, your volume would be close to 85 litres. Remember, only Han Solo can convert light-years into parsecs due to being written in America.
@@etherealbolweevil6268my volume is way more over 85 liter because i'm nearly 2 meters high and i need about 1 square meter to fit in a space so i'm 1x2= 2 cubic meters and 2 cubic meters of water weighs 2 tons...but yes i'm not 2 tons

Am I alone who finds it kinda scary, how he took all those jokes about Von Braun seriously? I guess it is okay to not know anything about who build a rocket that took their nation to the moon, but this poor fella doesn't seem to even know what a WW2 is.
Customary/imperial is complicated because each unit in the system was conceived of independently. Then later they were tweaked slightly to make them "easily" convertible. Three barleycorns in an inch (which is the width of a thumb), twelve inches in a foot, three feet in a yard (which is roughly one pace), 5.5 yards in a rod, 4 rods in a chain (this cain was a common measuring implement in surveying), 10 chains in a furlong (which is the length a team of oxen could plow without needing a break), 8 furlongs in a mile (a mile is about 1000 (mila) double paces) Using body parts as definitions for measurements stopped being sensible when we stopped using body parts to measure things.
It's all about politics and old people. President Ford signed the Metric Conversion Act into law in 1975. It passed Congress with little opposition. President Reagan blocked the conversion to the metric system in 1982 with an executive order which abolished the Metric Conversion Board which was overseeing the process. Mainly because old people were opposed to metric and they vote in big numbers.
I graduated high school in 1978 & immediately went to nursing school where I first learned the metric system, I could not believe how easy it was to learn because I hated Imperial math!! I barely passed imperial math but metric was a breeze!
The Netherlands was under the rule of Napoleon Bonaparte and converted (after defeating him in Waterloo) into metric since 1816 but old school measurements cleverly stayed by defining them in metric: ons (ounce) = 100g; pond (pound)=500g; pintje (small pint)=250ml, until after WWII people were used to talk about the weather in degrees Fahrenheit, but that is totally ancient. I never understood this because the Celcius scale is so easy to calibrate: melting ice = 0 °C and boiling water = 100 °C.
"he desigend a rocket to fly to England to show them how much better metric is" means that he build rockets in WW2 to shoot and attack at england with rockets

In Austria, and I think, whole Europe Inches are just used for hoses and pipes by plumbers. No idea why. And for ammunition calibers, differs between military or hunting rifles. I'm aware as a Technician with Inches, but that's it on your system.
3 countries out of 195 have not adopted the metric system, this alone closes the debate.

Using the Imperial system what weighs more. A pound of feathers or a pound of gold. If you think it is the same then you are wrong. It is the feathers. For the explanation go to Nerd Nite #5: Metric System Lecture on the TH-cam channel of Randy B. and go to the 19:56 mark. That whole video is a perfect showcase of why Metric is better, cheaper, easier, and kills fewer people than Imperial.
Regarding having to memorize and multiply/divide with all those conversion factors within our version of the Imperial system, John Q. Adams in 1821 reporting on the question of switching to metric wrote: "No one can easily forget his youthful attempts to memorize long and generally almost meaningless tables and to master the mysteries of addition, subtraction, multiplication, and division of 'compound numbers' . . . Conservative educators have estimated that the use of the metric system . . . would save one to two years of the school life of every child." One to two years of our schooling taken up by learning to use the Imperial system compared to less than an hour needed to learn to use the metric system. In elementary school our arithmetic books always had a conversion table for Imperial which I used constantly. Then one year our book left out that page and I was lost all year. Over half a century later, I still haven't memorized how many feet are in a mile. I'm all for switching to metric, though I am well aware of several problems with the process of switching over. Funny story about metric ignorance. As gasoline prices were rapidly approaching $1/gal round 1980, gas stations with mechanical pumps (ie, almost all of them) that weren't designed to deal with prices per gallon at and above $1 were desperate for a solution (which turned out to be replacing them all with electronic pumps). Since we were supposed to be switching over anyway (stopped by Reagan), one station in Nebraska decided to start selling gas by the liter -- the price per liter is about a fourth the price per gallon. Posting prices per liter led to motorists flocking to that station. Of course they were forgetting that a liter is about a quart and about a quarter of a gallon. Even when the TV reporter pointed out to one excited customer that that price wasn't for gallons but rather for liters, she was still ecstatic over such "incredibly low prices."
Noticed the vid kinda expects people to get the joke regarding the lead scientist on the Apollo program. Most reactions ive seen in my random trawl today seem like maybe they miss the humor.. The scientist is Wernher von Braun, a Nazi recruited from Germany after WW2 in operation paperclip.
I'l give you a nice example. I work in a factory. I measure cables everyday with precision down to 0.1 mm. And you can do it with completely analog tools. And some people in my factory measure wire strands with precision down to 0.001 mm. Try doing THAT using imperial units!
I think you missed the point here. Using metric does not magically make your measurements more precise. You still can have the same analog tool with an imperial scale and get the same amount of precision.
It's a demanding process : you can easily convert any volume to any mass to any distance from mm to km in a flash , but, Behind this apparent simplicity you have first to know how to count from 0 to 10.
As 'British Empire' spread, the official Imperial System of measurement came into force in 1826 (it was also known as the 'Exchequer Standards' measure, because it was used for taxation purposes across the 'Empire). It ensured that those countries influenced by Great Britain would all be weighing, measuring and calculating costs on an even footing. Before that date we used the 'English System' (or 'English Units' of measurement), which evolved as a combination of the Anglo-Saxon and Roman systems of units... But typical of the UK, we still like out traditions, so although we officially use the 'Metric System', we still order milk and beer by the pint and measure our road distances in miles. Good old Blighty. 👍😄🇬🇧
In one sentence: Within the imperial system you have calculate conversions from unit to unit (12 inches in a foot, 3 feet in a yard, 5280 feet in a mile...), whereas in the metric system you don't because all the ratios are multiples of 10 just like our numbers.
you can shift a point or you can shift your brain The advantage is that the number does not change in the metric system, only the point is moved: in meter: 12m in decimeter: 120dm in centimeter: 1,200cm in Millimeter: 120,000mm and it is scalable from the smalles part of an atom to the size of the univers without any rounding error all units are connected with factor 1: Water: 1kg is 1dm³ is 1 liter or 1000: 1kg=1000g=1,000,000mg 1N=1m/1s² push the point instead of multiplying by 0,000568182 or 1760,0005632
The French ship, that tried to bring a meter and a kilogramm to the new United States, was boarded by pirates. And now you think about the cost of having your actual measurements tranferred into metric. But Great Britain did it several years ago. First they used both measering systems side by side, and when a sign on the road has to be changed, it was changed into metric. Today the youth use metric as a standard and only the parents still know, what it was in imperial. Just start it, an in twenty or thirty years, everything is fine. It was the same, when all the other countries in the world did it, they also measured befor in other types of feet and mile, onze, etc.
but the UK is converting to stupidity right now, so i would not hope they know what they doing, and metric is French, France is in the EU, they hate France, they hate the EU!
In a video by Neil DeGrasse he allready stated that Americans allready use metric. How much Coke is in a bottle or how much beer in a bottle or can. Or when you look at a product in a supermarket. How are the ingredients like sugar and fat specified? Other fun fact. Here in the Netherlands most measuring tapes also have inches on them 🤦🏽♂️
Metric is only _slightly_ used by US Americans in daily life: People know what a two-liter of soda is, but they don't actually use liters for anything and most soda sizes are based on customary units. Nearly every item in the store is primarily customary, with a metric conversion beside it that Americans freely ignore, partly because they're just ugly conversions from the units they're used to; there are a few exceptions, such as water bottles all being 500 mL, but it's still pretty common for Americans to focus on the units they're most used to regardless. Nutritional info (grams of fat and protein, etc., and calories of energy) is metric, so we're used to metric units in those cases - but while sugar in nutritional info is metric, bags of sugar and sugar in recipes are primarily customary. Medicine dosages (mg and μg) are also metric. All of science, auto industry, most of government, half or more of engineering, and most of health services are metric, but this doesn't apply to daily life. Construction is still fully customary, aswell as most other kinds of occupations other than those I listed as being metricized. Interesting that most of your measuring tapes are still dual-labeled. That sounds like a pain to deal with - atleast you're not in the US, where the most common measuring tapes are _inch-only._
The answer to the question why the US still uses imperial… money! Just think about the cost to replace ALL trafficsigns with distance and speed in the whole US… insane! For example 1 trafficsign to replace $250,-..?…. ( production and replacement)
I love to watch Americans react to this video. Dude did an awesome job and greatly portrayed the problem with Imperial system. Although i can imagine as a European that changing a measurement system in a country that is made from different states with such a big number of residents would be a government nightmare... Still i think that as a united species we NEED to use one measuring system. There is also a topic of a temperature measurement which also is better in Celcius. Idk know how the hell you're not using this... Also when i watch some nice food recipe videos on YT and see all those cups, ounces and other attrocities im just like "nah brah i can starve to death thank you"
Just change one part of the measurement system at a time, so year 1 - pints and gallons become bushels in texas, year 2 bushels become litres in texas, pints and gallons become bushels in ohio, miles become furlongs in texas, year 3 furlongs become centimetres in texas, miles become furlongs in Ohio, pints and gallons become bushels in hawaii , bushels become millilitres in ohio. You see, not one instant of Federal Regulation is needed, every state can pick its own conversion rules and units, there are so many to choose from.
The US doesn't actually use the "imperial" system. The imperial system was formalized in the 1820's; the US would scarcely have signed on to such a system (there had been some unpleasantness with the Brits about 10 years before). The imperial system was devised by people who used "12 pence to the shilling, 20 shillings to the pound ... and then there were odd things like guineas which are 21 shillings, but were no longer minted after 1814, though they remained in accounting terminology. ) The US uses the much older "common" measure ("Queen Anne's"). However, Jefferson was in favor of the metric (among others). Metric seems to be particularly common for global sales ... so John Deere would use mostly metric. I think Caterpillar is sort of a holdout, but that seems more tied to the (massive) expense of re-tooling. Having to make completely new castings for (say) just the multiple forms of pistons used on their heavy equipment ... Still, it gives some of their competitors (Hitachi?) an advantage, so it seems like something they will have to do. I think it will take longer before peaches (say) are no longer sold by the pound at the supermarket. Well, just a thought.
Take one meter and divide it ten times Now you have a decimeter Make cubic container with 1 decimeter sides Fill the container with water and you have one litre Put the container in the freezer When there is a mix of water and ice you have 0 degrees Celsius Heat up the water and when it starts boiling you have 100 degrees Celsius.
Fyi…. There are no conversions involved in the bridge example. It is just measuring distance. 12” in 1’ and 5280’ in a mile. So the number of inches in a mile is not a conversion, it is a calculation.
America doesn't use the Imperial system it uses a variation of it. Look up the conversion between a UK quart, a US dry quart and a US wet quart and you will get three different figures. the UK one is the Imperial one. Fluid ounces and gallons are also different between the US and UK.
The US's imperial system is based on the old Queen Anne imperial system. British imperial was later reformulated in terms of metric units, and by a strike of luck, our pints grew significantly larger.
The funny thing is, that they use metrics for they money. If they love imperial that much, why don't they use the old english pound system. I mean that together with the fact that taxes are not included on the prices you see, that should be a lot of fun 😄😄
Most annoying part as engineer is that imperial uses fractions instead of decimals. What the heck is 35/64 of an inch. just say it's 0,546875 inches. NOOO we use decimals like 0,55 inches, that's too confusing. unless it is more accurate measurement than fraction of 64, then we might just use decimals. Oh an in adition we can mix and match 35/64 inches with tolerance of 0,05 inches! Amazing. You need a guide book to use imperial metrics and converting metric to imperial in a way that it makes sense in fractions forces to make measurement changes. Cant just convert with factor.
The reason the imperial system is such a mess is how it came about. It was based on purely human concerns. An ounce, for instance, might be defined as 'the weight of an egg'. Problem is, of course, that eggs vary in weight, and so what the _accepted_ weight of an ounce is would vary from place to place. So you'd be in one town and they'd have weights they specifically use for measuring that are what they call 'an ounce', and then one town over the 'ounce' would be based on a similar but slightly different weight. The 'foot' was originally defined as the size of the king's foot, which would, of course, vary from kingdom to kingdom and also every time a new king took over. Probably not by much, but small differences add up. Eventually merchants got sick of this because it caused headaches for them and pressured kings and such to 'standardize' the system. A foot became some fixed length, an ounce a fixed weight, and so on. At first this held within a country, and eventually got spread when England entered it's Empire phase and forced all the places they invaded to use it, too, which facilitated trade. And yet the pound would be likewise based on something like that and then they'd work out what the conversion was between ounces and pounds. Each individual method of measuring the same quantity, each _unit_ of measure, was arrived at independently of the others with no consideration for the other units being used, and conversion factors were just a matter of calculation, even after they were standardized. Metric came along at one point because they recognized the silliness of a system that operated this way. They based it on base-10 counting since that was the most common where they were. However notice that there's still 'magic numbers' involved, (like the meter being defined by how far light goes in 1 over 299,792,458 seconds. Why that number? Why 299,792,458? ... Because that'll make it match what a meter is based on badly measuring half the circumference of the Earth and dividing by 10,000 (which is where they got the meter in the first place). Wouldn't it make more sense to start over, have a new system, and make whatever we call the base unit be the distance light travels in 1/100,000,000 seconds? Much nicer! One reason that this doesn't matter, though, is that you don't need to memorize that number, 299,792,458, to _use_ metric. The definition doesn't much matter. Unlike the imperial system where in order to use it you _do_ have to memorize the number of inches in a foot, feet in a yard, yards in a mile, and so on. Another issue is why we're using base-10. If we were going to restart, make a new measurement system, let's change the number system while we're at it. With the way computing works, it would seem to make sense to switch to base-16. Right now when we look at computer values and code, it seems like a foreign language. Computer storage looks like this: 01 23 A4 2B 44. That's because it's in hexadecimal (base-16). But because we don't _use_ base-16 in our everyday lives, we can't really 'read' what that's saying. If we wrote the same thing out in decimal, it would read 001 035 164 043 058. You can _read_ that just fine, you know _exactly_ what that string of numbers is, even if you don't know exactly what it _means,_ and you can even combine them. You can read 035164 as a number and understand it, but try that with 23A4. Even if you converted each segment you can't easily combine them. If we could read hexadecimal as easily as we currently read decimal, that'd be a superpower for dealing with computers. Given how much computers run our lives these days, that might be pretty useful! Or perhaps we could go back to the Roman idea which has some serious utility. Go with base-12 counting. The nice thing about base-12 is that has several useful divisions that are extremely common with pretty much every human thing we do. When you look at 10, it's evenly divisible by 2 and 5... and that's it. You can easily get to 'half' of a quantity, but if you want 'a third' or 'a quarter', both of which are really common things to need, the math gets harder because you start needing decimal places and so on. But what about 12? Evenly divisible by 2 _and_ 3 _and_ 4, not five but also by 6. Those are some pretty common ways that we split things. In fact 2, 3, and 4 are the most likely ways we'll ever split anything (two people, three people, four). Six is pretty common, too. On the other hand, back to base-16, you can evenly divide that by 2, 4, and 8, also rather common divisions that show up pretty frequently. In both cases you can get a length unit that is _close to_ the current metric one (I don't know about the others, to be honest) while being easy to remember. Sticking with base-16 (which I think is the better idea), The number '10,000,000' in base-16 is, in decimal, 268,435,456. That's pretty close to 299,792,458. It would mean the unit of length would be 89.5% of the size of the current length, but we could adapt. Of course, this presumes the 'second' remains the same, but you get the idea, we can pick a 'magic number' that is a power of the base of the system for the measurement, which would make even remembering _those_ values easy. I _also_ think we need to get a metric-style definition of time. So pick one unit (second, minute, hour, realistically something entirely new), and make the other units a base-power multiple of that. In decimal we could, for instance, have seconds, decaseconds, and centaseconds, each being a multple of 10 difference, so ten seconds in a decasecond, 10 decaseconds in a centasecond. No conversion. The one thing that would seem to be 'bad' about this is that a 'day' won't be some nice number. It won't be '24 hours', for instance, but might end up as 13 centaseconds 9 decaseconds 12 seconds. Which seems cumbersome. _However,_ there's a utility to be found here. Right now we live on just one planet, Earth, which is not a great strategy for long-term survival. We want to get off this planet. But if we do, _no other planet_ is going to have a day that's _exactly_ the same length as our own. Yet imagine how easy adapting will be if we understand when we get to a new planet or whatever that the 'day' (maybe we'd call it a 'rotation' by then) is just a different number of centaseconds. "Hey, we're on Mars. The day here isn't 13 centaseconds, 9 decaseconds, it's 13 centaseconds 12 decaseconds." Not really that much harder to adapt to than time-zone change. It'd future-proof us for when (if) we leave Earth and set up shop elsewhere.
In everyday life you can use any system, it’s not so important. But everything changes as soon as you are faced with engineering calculations. Here the advantages of the metric system are undeniable. At the end of the video, it will be noted that now the standards or benchmarks of weight or length are not physical objects made of metal, but a long description through formulas linked to eternally constant physical quantities (Planck’s constant, etc. So scientists thought that it would be more reliable than have a metal cube weighing 1 kg (after all, when slightly heated, the metal emits electrons into the atmosphere, and this is a loss of mass, for pure science this is unacceptable, but for everyday life it is acceptable.) Therefore, we decided to describe what a second, meter or kilogram is in terms of eternally constant values from world of physics and no longer make them from metal or anything else. For example, now 1 second is a time interval equal to 9,192,631,770 periods of radiation corresponding to the transition between two ultrafine energy levels of the ground state of a cesium-133 atom at rest at 0 K .
No american is noticing, that the "Alabama" Men was a German Nazi and he developed the first rockets for war - World War 2 to be exact... funny and sad at the same time.
I grew up and live in Germany, so I´m used to the metric system. There was however one big change of units during my livespan: the switch from Deutsche Mark as a currency to Euros. The switch was done about 30 years ago, with an overlap of three months, where both currencies were valid, after which the Deutsche Mark was phased out. Near the end of those three months, I found a 20 DM bill in a jacket I had not worn for some time and bought some fast food . The cashier really seemed to struggle for amoment, almost giving me a look he would give someone trying to pay with bills from the game Monopoly. On the other hand, despite 30 years between the switch and today, many Germans (including me) tend to convert the price of certain goods back to Deutsche Marks, just to get a feeling if the price is appropriate or not. Due to infaltion, most of the times, the answer of course is a loud: "NO!!!!!" Dispite the advantages the Euro brings (travelling between countries in the EU without having to bother getting some cash in the other nations currency, or when trading goods and money transfer), it is still rather unpopular, since almost any european citizen has a feeling that they were better of with their former currency (as alredy mentioned: inflation plays a big part in this). Long story short: The big project of agreeing on a very straight forward system of base units has already happend aroung the world, only America, Lyberia and Myanmar are refusing / used to refuse to switch. And to a certain degree, I understand why. Ok, inflation won´t play a role in the system of units. ;) But having grown accustomed to a set of units and converting to a different one is kind of like starting to use another language completely - and it is not the language you think in, you dream in. Despite the essential advantages of the easy conversions, the Americans will most likely think of a distance in miles, to have an idea, a gut feeling for how long it will take to got there by car, how much fuel it will take to get there, how much it will cost. If given the distance in kilometers, in the beginning, any one will do the maths to be certain, even if they first calculated based on metric units to get used to metric units. Just to be certain. And this gut feeling, this double checking will remain in the every day life for at least a whole generation, if not longer. Still, getting rid of conversion (and related errors) and misunderstandings, I think it is worth the efford.
America is changing slowly, buying foreign cars and Austrian 9 mm pistols, uses a military rifle of 1 m length using 5,56 mm bullets. You see, the change is on the way.
One ton used to be 2,240 pounds. Today it is 2,000 pounds. One imperial pint is 26 ounces. An American pint is 24 ounces. 12 inches = 1 foot: 3 feet = 1 yard: 22 yards = 1 chain: 10 chains = 1 furlong: 8 furlongs = 1 mile shows how insidiously convoluted the imperial system is.
1 tonne is 1000 kg. 1 litre of water is 1 kg. 100 cm is 10 decimeter is 1 meter. 1 kilometer is 1000 meters. 1 joule is the energy needed to lift the temperature of 1 gram of water by 1 kelvin or celcius. 1 watt is 1 joule per second. The only thing that defies logic is the clock with ancient 12/24 hours and 60 minutes and 60 seconds units.
The only people that ask that question "is the metric system better?" Are Americans, the rest of the world uses the metric system and already know it is far better.
Anyone that has taken even high school science knows that metric makes more sense. And if you've done any college level science, you laugh at those who still insist on a system designed by those who marry their cousins. 5:15 - That's NOT video of the "Gimli Glider" landing. The Air Canada plane landed intact and took off after being refueled. The abandoned air field mentioned was a military airstrip turned into a racetrack, and there was an event that day. Everyone goes racing with fire extinguishers, so there were plenty of rescuers and no injuries. 9:00 - Why doesn't yankland change? Because of the arrogant assumption that it "knows better than everyone". It's also why the yanks refuse socialized medicine, safety regulations, representative government (no, you don't have one), etc. 11:38 - Caesium is used because it's the only atoms that constantly vibrate the same number of times per second.
The reason that it doesn’t change completely is that the government gets too much push back from its citizens to make such a huge change. Australia did it in 1966 and it was relatively easy. It takes a lot of planning and of course there were objections, but once implemented it was easy to adapt. Mind you I still think of height in feet and inches to imagine how tall someone is. But a metre is about 3” longer than a yard so it is easy to have a rough idea.
I can understand the force of habit... and personally I think: hey, people can quit smoking. Which is addictive, psychologically and physically. So why can't they stop to "think" in feet and inches? Yes, habit... and no repercussions. But I seriously wonder why someone would give their height in "a few of these units, and a few of those units". Unified decimal systems are just so much more convenient.
If you work in science or engineering metric makes the most sense. Britain uses a mix of metric and Imperial depending on the context. Beer, plumbing, pressure, measures of energy from vaporous gas, rail gauges and office space work well with British units but for nearly everything else metric rules.
Short answer: yes. It is actually better. Otherwise, the US government, military and the scientists wouldn't use it. The USA government twice accepted a Law to enforce the Metric system in America.
When I first started work in 1971, I had been brought up thinking Imperial and to change was a bit of a struggle. However once I got over it, to add two imperial measurements is more complicated. 1 3/8 + 2 1/4 =??? You have to bring the measurement to the lowest common denominator 1 3/8 + 2 2/8 = 3 5/8 Working conversions 1 3/8 = 0.03493 which is approximately 35mm 2 1/4 = 0.05715 which is approximately 57mm so adding these two numbers become easy 35 + 57 = 92mm easy peasy All that being said, I still use mileper gallon to understand if my car has a good petrol comsumption and although I use meters with work, I talk about miles when talking about distance between towns or miles per hour when talking speed. My brain has a better visual on those rates for me to comprehend the concept. Ohh well you can't have it all. lol
And that's why we in Europe asked ourselves in middle-school, why do we need to learn mixed numbers when nobody is using them? 😏 By the way, we calculate petrol comsumption in litres per kilometre (usually in hundreds of kilometres), not miles per gallon. It's the other way round!
@@jtommygun It must be complicated for the military to constantly switch from one system to another! For example, the capacity of the tanks is in liters or gallons? Are the times between 0 and 24 or with AM PM?
@@couvertgerard7742 yup, you see all the time in the movies something like, "we meet at zero eight hundred hours" 0800 is eight o'clock in the morning, the time is always in 24 hour format, without forgeting the leading zero when is necesary, or "we are five klicks from the road", klick is jargon for kilometers. etc.
or most likely took a sadistic Grifterian delight in making everyday life more complicated than necessary for the rest of the world when they have to deal with the quirks of the United States of America.
But wait, there is more. There are more units that sound the same but mean different sizes. Gallon in the UK and gallon in the US, anyone? And then go to very "logical" ounces etc.
3 countries are uysing imperial system but most Americans now think there are 4. USA, Myanmar, Liberia and the 4th - Europe. I`am not kidding I watch Jay Leno`s street interviews
in the first half minute, the video starts already with missing knowledge about which system the usa use ... although many people call it "imperial", it's different, there used to be several imperial systems, and the current system is legally defined by conversion factors from the metric system and SI units.
But we British still have not let go of imperial. We hold on to bits of it with white knuckles, like our Pint of beer, but we have no hangups with grabbing a litre of milk at the corner shop. Most people describe their hight in feet/ inches. And road speeds and distances are still in MPH and Miles.
Its crazy to think that the french revolution created the metric system but in the americsn revolution americans kept the literally "imperial" british system, its like wtf bro
So if a 1 cubic metre of water weights 1 metric ton (t) or 1000 litres (l). 1 litre of water weights 1 kilogram (KG). So if I'm going shopping and buy 5 l Milk and 2l of soft drink I'm carrying about 7 kg in my bag. Simple.
Just for puntualization: 1 litre of water is 1 Kg, but 1 litre of some other liquid is not. It depends on the density of course. But this is not a measuring system issue, it's just physics
@Gianninnn You're right. What I said doesn't comply with the AS 1100 it should have had no punctuation and all in upper case except for the abbreviations accepted by the standard in lower case. Yes, some liquids do not have the same density as water.
It was stated in the video, just like all the other basic units its definition is based on a scienetific observation inserted with the rest into a comprehensive whole. If i remember correctly the ceasium 133 isotope was used because its "vibration"-fequency remains very stable even if there is interference from outside. So time as any other basic unit stays "relative" in reality, but theory needs to be backed up by useful facts, the error of some ceasium 133 atomic clocks is somewhere at 1 second in a bunch of million years, more accurate "clocks" are beeing invented.
@@jukopliut You'd still need to operate a atomic clock as a whole body at light speed, because of static speed and no velocity there should still be a unchanged condition regarding the measuring itself. As for fringe effects etc., for example the theory that the perception of time would slow the faster you move, ask a physicist... or ChatGPT...
@@jukopliut That's not how it works. It "vibrates slower" from the point of view of someone in a different frame of reference (i.e., the observer to whom it is moving "close to the speed of light"), but just the same to someone travelling alongside it. You can only properly measure things in the right reference frame.
a whole 3 washing machine wide has opened. american will use anything but metric system to describe things :D. sry for a joke :D love your reaction on football fans and i guess yt algorithm offer me this video. plus it was great. we in europe learn some stuff in difference between system and this was even better. thanks man
@GH1618 I don't know why you think that.... The International System of Units (SI), commonly known as the metric system, is the international standard for measurement. The International Treaty of the Meter was signed in Paris on May 20, 1875 by seventeen countries, including the United States
I like to watch old car videos. They talk about how much miles per gallon. I dont know how good or worse it is🤣. Just say how much kilometrs per liter.
All you need to know in the matrix System is how to properly shift a point from left to right or vice versa.not that hard. For all who love fun videos:Happy phun time farm: the metric system is bulldoggery is great!!!❤
It doesn't make sense to ask which is best because both do the same jobs. However which is simpler? Well clearly metric is far simpler as it uses factors that make doing the sums far easier. Now I grew up in the UK where both systems were common and to this day most people measure their own height in feet and inches, their weight in stones and pounds, and the roads are measured in miles and speeds in miles per hour. But ask the scientists and engineers in the UK and it's almost certain they will talk in terms of metres, centimetres, kilograms, kilometres and kilometres per hour. Having two systems is usually blamed on the older people not being used to the metric system, but then now I am one of the older people and see people my age who were educated in metric still reverting to imperial. Now I am living in the Netherlands and here everything is metric but it does have a legacy and very occasionally you encounter that. For example at the market stall you can order fruit and veg in pounds (actually pond) which is now 500 grams. To give you an idea of just how confusing the weights and measurement system used to be, in the 1820s we switched to metric but before that there was not just one single definition of pond, we had at least 9 different regional definitions of pond which varied from 275 grams up to 497.8 grams. So introducing a standard of 500g made perfect sense when metric was introduced. Then we have another old measurement that is not actually used and that is the duim (literally thumb) and that is where the rough length inch comes from (the top part of the thumb back to the joint). The phrase duimstok (thumb stick) is a reference to a type of wooden folding measuring device that you might have seen used by certain professions but has largely been replaced by a tape measure. But interestingly the phrase "rule of thumb" comes from the use of this vague measurement.
A cubic centimeter of water in the metric system is 1 milliliter, weighs 1 gram and 1 joule of energy raises the temperature of this water with 1 degree Celsius so everything is nicely connected.
And try to convert 2 galons into feet hahaha. Yes metric is common sence and imperial is stupid
@@jannowak2352 Small correction: one calorie (former unit of energy) raises a gram of water by 1°C or 4.18 Joules. The metric system is awesome but nature is tricky. The Joule is defined as being the work of a motive force of one newton whose point of application moves one meter in the direction of the force
No. It depends
@@kolimarvelcor3104 yeah, almost. You mix Joule and Calorie and break 'unity', s'all good.
my remembrance [ from the 80's ] is the Specific Heat Capacity is [ roughly ] 4,200 joules/liter/degree C. that makes exactly 1 Calorie. [ 4,184 joules for accuracy Google'd ]
Science. Love it.
I am an engineer in the US. The companies I have been working at made the transition to metric around 30 years ago. I think we should start moving the community over to metric by adding the equivalent metric units in signage and state regulated packaging (I think most nutrition labels have started to list sizes in grams, which is a start.). It’s just a matter of practice to get an intuitive feel for metric sizes vs. imperial, so let’s get started already.
Deny the future the sheer joy of working out if a thread is BSW, ME, BA, NPT, BSP, JIS, SAE, and revealing the magical TPI. Shame on you. The whole thread gauge industry would collapse, there would be moral panic, dogs and cats living together, the whole book of revelations thing. Any nation capable of grasping hundreds of cartridge sizes and types and never ever loading a .45 with 9mm, is ideally set to cope with the continuing 'simplicity' of imperial fasteners. Not to mention the improved simplicity, of course, of inventing its own standards to protect its own industry and not have to deal with the evil British way of measurement.
I think the dual messaging is a fantastic idea. Even road signs... 5 miles (8km). People don't want to convert to metric because they don't know it. It may take a generation, but the longer term benefit is worth it.
@@_Dei_ You are correct, I was born when South Africa changed to metric. Well at 62 I still get to work with imperial measurements. Machines were made to last before 1960.😂. To name one wood sizes is still in inch, everyone know what a 2x3 is but not what a 48x 70 is, by the way it is the same piece of construction lumber.
@@henningventer2917True. But when you use imperial you also have subunits, like 2/5 etc. inches and so on. That is soooo complicated. Pipes sizes are many times still in inches even in Europe, for now. One has to completely quit the mixture at some point.
@@ContraVsGigi yes you are correct, like I said monny is holding us back. Take any city in the world, how many miles/km mainline piping is tbere in it? Now start to replace it with metric sized piping, remember you need atleset 1 spool piece with metric and imperial flanges to connect an new metric section.
Here is a tip for you how to get it.
Do not compare imperial and metric.
When you decide to use metric for a project just use a ruler, measuring tape in metric and skip the conversion in your head.
You do not have to have a feel for how much is a meter like you would have it with say a yard.
The biggest advantage is. You can throw the calculator away.
1 kilometer=1000 meters (Kilo=1000 used for making big numbers smaller)
1 meter=1000 millimeters. (Mille=1000 used for making small numbers big)
1 meter=100 centimeters. (Cent = 100)
1 meter=10 decimeters. (Deci=10)
...and that's how metric works.
Easy, isn't it?
Now you can say without calculating it what half a meter would be in millimeters or centimeters, can't you?
I guess dividing by two isn't as hard as fractions of 7/8 of an inch or something similar!
Five tomatoes and such bs.
"You do not have to have a feel for how much is a meter like you would have it with say a yard." given how much your feel for a yard changes while growing up and all that, i'd argue that's rather fast to learn though. but then again when you decide to use any measurements for a project, you should be yknow *measuring* them anyway, so why not do it right :P
btw metric doesn't even make much sense when it's used, eg 2-by-4s are neither 2 nor 4 inches long so yeah i'd rather get a 5x10cm plank to size, than an "not 5,08 by not 10.16 cm" one with a fancy name :P
*and* you don't have to figure out if your not-2-by-4-in sized pillar still fits in the "13438/16ths of an inch minus 5/8th of a pound" hole if you're already using decimal numbers like you wanna do your math efficiently instead of in "slices of an apple" like 2nd grade :P
@@nonchipThe imperial subunitary measures are a complete alien mistery for one used to metric. How on Earth can one torture himself/herself calculating things like 5/7 + 12/19 or so? :))
I was brought up using imperial measurements until I was 14 and then we changed to metric. Soooo as someone who knows both, I can tell you that metric is far easier to use and is more accurate
Metric is definitely easier and better, but never say it's more accurate. As they say in the video, imperial units or actually US Customary units are defined in metric, so there is absolutely no accuracy to be gained, both are equally accurate.
@@tomfredrikblenning9054 for sure is the metric system more accurate.. 1 inch is 25.4mm so the resolution is more accurate
@@shreddiest that is a false argument. You can always divide into something smaller. A twip (yes I know - nobody ever uses it - but it exists) is 1/1440 of an inch or about .01764 of a mm. Which again is about 17.64 μm . You can be as accurate as you want with both systems. I think maybe the argument you are trying to make is that the common denominations of the SI-system lends themselves to more accurate measurements. That is an argument that may have some merits.
@@shreddiest Any proponent of customary will trot out the argument that Fahrenheit is the more precise unit than Celsuis.
You can use the necessary number of decimals in any system to achieve the necessary precision. Though it's definitely easier if you have a system that uses consistent steps of 10 or 1000 between units.
I worked at a company (Australia) where we supplied Australia, New Zealand, some parts of Asia and America with very high end customised doors. When the Americans were getting started they actually came over to Australia to understand the manufacturing and assembly process so they would know how to install and do repairs. As we needed all dimensions supplied to us in metric they purchase a heap of measuring tapes etc while they were here. They said that it was too hard to find anything with the metric system on it in America. I was dumbfounded.
You didn’t say when that was, but it certainly isn’t true now. If you just go in your neighborhood hardware store, they may not have a Metric tape, but you can shop online and find several easily.

All you need to use the metric is being able to multiply or divide with 10.
.. basically just shift the decimal point the right direction....
Although I don´t understand .. but there are people finding "divide by 10" similar difficult than "divide by 9" .. but they find it easy to shift the decimal point.
A hint from the rest of the world. No one is considering changing to imperial. No one!

There is a straightforward answer to the question "why". You only have to see the videos where random people are asked simple questions like "what is 3x3x3" or "can you show a single country on the map". After watching them the answer is obvious.
Come on, not all Americans are stRupid. I know a few very smart ones. But this change has to be pushed and enforced. They did try changing a few decades ago, in the 60s or the 70s I think, but it was only partial and optional. That does not work.
@@ContraVsGigi Of course not all of them are that stupid, but in a normal European country you cannot find people who are so silly as those shown in several videos.
@@ContraVsGigi Partial could work, but optional definitely not. Like... units could be replaced 1 by 1 instead of all of them at the same time. That would be likely to meet far less resistance.
@@ContraVsGigi You don't have to push the changes to the general population. Just start teaching metric only in schools. Making daily measurement changes may have catastrophic consequences. For example changing the speedometer and speed limit units may cause issues. However that would indeed be the fastest method. You guys already use metric units in many places and slowly you guys are starting to use metric more and more so Im sure over time you'll switch over completely and measurement of length will be the last one to go.
For example here in India we use metric for everything, literally everything even length. However, we still use imperial colloquially for our height. Officially we use cms for height measurement but if someone in the street asks us how tall we are, more often than not they expect feets and inches. This is kinda weird when we think about it but we're just used to it.
From an european point of view, this neolithic imperial system still lives because of US arrogance : After WW2, USA felt so powerful that they thought they could define all world rules (and nature laws, since metric system is based on natural physical constant things) ... Only americans still ask themself such a question. Rest of the world has a metric answer since a century. Please consider changing to Celsius temperature also.
If you need some motivation to change, just think about it : whereas USA did lead the last century tech race, i don't know (or never heard of) any american mathematician...
wtf ?
**here is what they didn't teach us... the centimeter is a drop of water on a non-porous surface. Check it out. It is a constant, everywhere.

The guy at the beginning of the video is Wernher von Braun, a German Nazi who built the V2 rocket for Hitler (using the metric system of course) and later was forced to work for the US to extend his V2 to a rocket that can fly to the moon. Just for reference, since nobody seems to understand the cynicism in that part of the video.
He was not forced.
The first time I watched that video, the unexpected joke about 9, "nein, nein, nein", LMFAO.
Edit to add: I knew about von Braun, I speak a bit of German, I was/am always interested in History, born and raised using metric system.
I was in elementary school back in the early 70s when the government was working up a plan to switch the US over to the metric system. It was a failure, but I really wish they'd stuck with it. As young as I was I would have learned it and been comfortable with it like the rest of the world.
It wasn't a failure. You have Ronald Reagan to thank for that.
Just him screwing over the USA once more.
His reason for it was that he thought it would be to expensive. Yep, the guy that had no problem funding death squads or making backroom deals with terrorists and hostage takers couldn't even understand how being one of only a fer few countries left not using it would be detrimental for the USA.
It was partial and optional. It does not work if you don't enforce it, tradition and customs die hard otherwise.
96% of the world population uses the metric system.
Simple conversions to keep in mind:
a cube of 1 meter size, is 1000L
1m3 full of water , has a mass near 1 ton , which means 1000 kg
so 1L of water is very close to 1kg
when you have this in mind, you can think very quickly for a lot of day-to-day things
Thats, why people thinking in metric, gives the volume as a qubic of a length and not in gallon or barrel. Thats much easyer.

Just forget about the conversion, and all those crazy numbers at the end of the video. That is mostly just confusing, but the 10 base is the real important thing. While imperial, i think length is based on 12 but your numbers for fluids are even based on 16, so its all a total mess.
it almost sounds like measuring things (in a modern age where you do engineering, computers and high precision things) in feet, hands, toes and potatoes, oh and stones, isn't really a smart idea? Just a thought....
I'm 12 dicks tall, weigh 2 beer bellies and 4 oranges. I drink about 3 skull a day.
Just yesterday, I watched a video where "acres" were mentioned, so I looked it up:
1 acre is the area of 1 chain X 1 furlong, 1 furlong is 10 chains, 1 chain is 66 feet (calculate yourself, how many square feet or yards that is). 640 acres make a square mile.
1 acre is also roughly 0.4 hectare. What is a hectare? 10,000m² or 100m X 100m. 100 hectare = 1km²
I wonder if you can spot the difference in simplicity.
Ah, imperial is so much easier. Oh, wait... :))
@@ContraVsGigiHa ha!
People (US-Americans and elderly British) tend to view the imperial/US-customary system as more intuitive, because they grew up with it, which is only natural.
There are also legacy units still lingering around all over the world.
I mean: Everywhere, we still use inches for tires, dpi for print qualities, calories to measure the energy value of food etc.
It is obvious that the US won't ever switch from one day to the other to metric. The financial cost would be just too high and, although unnecessarily complicated and cumbersome, it somehow works.
However, it would make sense to start to always display both units in equal size and to teach predominantly metric in schools.
@@mina_en_suiza Yes, of course that is the process. People need to understand it first and get used to it. After a while you just makes things with yhe metric label and slowly you start replacing odd sizes with rounded numbered ones. It will work and does not need to be done over night.
Lol. America uses imperial and the UK uses metric.
And.... pretty much every other country on earth.
in metric you just have to move the dot to convert from kilometer to millimeters
i'm nearly 2 meters high which is 200 cm or 0.2 decameter or 0.02 hectometers or 0.002 kilometers or 2000 millimeters

I guess it is okay to not know anything about who build a rocket that took their nation to the moon,
but this poor fella doesn't seem to even know what a WW2 is.
Customary/imperial is complicated because each unit in the system was conceived of independently. Then later they were tweaked slightly to make them "easily" convertible. Three barleycorns in an inch (which is the width of a thumb), twelve inches in a foot, three feet in a yard (which is roughly one pace), 5.5 yards in a rod, 4 rods in a chain (this cain was a common measuring implement in surveying), 10 chains in a furlong (which is the length a team of oxen could plow without needing a break), 8 furlongs in a mile (a mile is about 1000 (mila) double paces)
Using body parts as definitions for measurements stopped being sensible when we stopped using body parts to measure things.
He did not get that joke about von Braun’s gap year.
It's all about politics and old people. President Ford signed the Metric Conversion Act into law in 1975. It passed Congress with little opposition. President Reagan blocked the conversion to the metric system in 1982 with an executive order which abolished the Metric Conversion Board which was overseeing the process. Mainly because old people were opposed to metric and they vote in big numbers.
I graduated high school in 1978 & immediately went to nursing school where I first learned the metric system, I could not believe how easy it was to learn because I hated Imperial math!! I barely passed imperial math but metric was a breeze!
Everyone use the imperal?
That was a good one 🤣
Personally I never understood why volume is measured in Floating Australians (Fl Oz)
The Netherlands was under the rule of Napoleon Bonaparte and converted (after defeating him in Waterloo) into metric since 1816 but old school measurements cleverly stayed by defining them in metric: ons (ounce) = 100g; pond (pound)=500g; pintje (small pint)=250ml, until after WWII people were used to talk about the weather in degrees Fahrenheit, but that is totally ancient. I never understood this because the Celcius scale is so easy to calibrate: melting ice = 0 °C and boiling water = 100 °C.
"he desigend a rocket to fly to England to show them how much better metric is" means that he build rockets in WW2 to shoot and attack at england with rockets

For the explanation go to Nerd Nite #5: Metric System Lecture on the TH-cam channel of Randy B. and go to the 19:56 mark.
That whole video is a perfect showcase of why Metric is better, cheaper, easier, and kills fewer people than Imperial.
Regarding having to memorize and multiply/divide with all those conversion factors within our version of the Imperial system, John Q. Adams in 1821 reporting on the question of switching to metric wrote: "No one can easily forget his youthful attempts to memorize long and generally almost meaningless tables and to master the mysteries of addition, subtraction, multiplication, and division of 'compound numbers' . . . Conservative educators have estimated that the use of the metric system . . . would save one to two years of the school life of every child."
One to two years of our schooling taken up by learning to use the Imperial system compared to less than an hour needed to learn to use the metric system. In elementary school our arithmetic books always had a conversion table for Imperial which I used constantly. Then one year our book left out that page and I was lost all year. Over half a century later, I still haven't memorized how many feet are in a mile.
I'm all for switching to metric, though I am well aware of several problems with the process of switching over.
Funny story about metric ignorance. As gasoline prices were rapidly approaching $1/gal round 1980, gas stations with mechanical pumps (ie, almost all of them) that weren't designed to deal with prices per gallon at and above $1 were desperate for a solution (which turned out to be replacing them all with electronic pumps). Since we were supposed to be switching over anyway (stopped by Reagan), one station in Nebraska decided to start selling gas by the liter -- the price per liter is about a fourth the price per gallon. Posting prices per liter led to motorists flocking to that station. Of course they were forgetting that a liter is about a quart and about a quarter of a gallon. Even when the TV reporter pointed out to one excited customer that that price wasn't for gallons but rather for liters, she was still ecstatic over such "incredibly low prices."
Noticed the vid kinda expects people to get the joke regarding the lead scientist on the Apollo program. Most reactions ive seen in my random trawl today seem like maybe they miss the humor.. The scientist is Wernher von Braun, a Nazi recruited from Germany after WW2 in operation paperclip.

I'l give you a nice example. I work in a factory. I measure cables everyday with precision down to 0.1 mm. And you can do it with completely analog tools.
And some people in my factory measure wire strands with precision down to 0.001 mm. Try doing THAT using imperial units!
I think you missed the point here. Using metric does not magically make your measurements more precise. You still can have the same analog tool with an imperial scale and get the same amount of precision.
It's a demanding process : you can easily convert any volume to any mass to any distance from mm to km in a flash , but, Behind this apparent simplicity you have first to know how to count from 0 to 10.
As 'British Empire' spread, the official Imperial System of measurement came into force in 1826 (it was also known as the 'Exchequer Standards' measure, because it was used for taxation purposes across the 'Empire). It ensured that those countries influenced by Great Britain would all be weighing, measuring and calculating costs on an even footing. Before that date we used the 'English System' (or 'English Units' of measurement), which evolved as a combination of the Anglo-Saxon and Roman systems of units... But typical of the UK, we still like out traditions, so although we officially use the 'Metric System', we still order milk and beer by the pint and measure our road distances in miles. Good old Blighty. 👍😄🇬🇧
And we have got a Pound (Pfund) in germany too. It is half a kilogram (better known as kilo) = 500 grams. So that 2 german Pfund = 1 kilogram (kilo)

In one sentence:
Within the imperial system you have calculate conversions from unit to unit (12 inches in a foot, 3 feet in a yard, 5280 feet in a mile...), whereas in the metric system you don't because all the ratios are multiples of 10 just like our numbers.

The advantage is that the number does not change in the metric system, only the point is moved:
in meter: 12m
in decimeter: 120dm
in centimeter: 1,200cm
in Millimeter: 120,000mm
and it is scalable from the smalles part of an atom to the size of the univers without any rounding error
all units are connected with factor 1:
Water: 1kg is 1dm³ is 1 liter
or 1000: 1kg=1000g=1,000,000mg
1N=1m/1s²

Companies do not want to pay the money to switch to metric and that is the only reason.

In a video by Neil DeGrasse he allready stated that Americans allready use metric. How much Coke is in a bottle or how much beer in a bottle or can. Or when you look at a product in a supermarket. How are the ingredients like sugar and fat specified? Other fun fact. Here in the Netherlands most measuring tapes also have inches on them 🤦🏽♂️
Metric is only _slightly_ used by US Americans in daily life:
People know what a two-liter of soda is, but they don't actually use liters for anything and most soda sizes are based on customary units. Nearly every item in the store is primarily customary, with a metric conversion beside it that Americans freely ignore, partly because they're just ugly conversions from the units they're used to; there are a few exceptions, such as water bottles all being 500 mL, but it's still pretty common for Americans to focus on the units they're most used to regardless.
Nutritional info (grams of fat and protein, etc., and calories of energy) is metric, so we're used to metric units in those cases - but while sugar in nutritional info is metric, bags of sugar and sugar in recipes are primarily customary. Medicine dosages (mg and μg) are also metric. All of science, auto industry, most of government, half or more of engineering, and most of health services are metric, but this doesn't apply to daily life. Construction is still fully customary, aswell as most other kinds of occupations other than those I listed as being metricized.
Interesting that most of your measuring tapes are still dual-labeled. That sounds like a pain to deal with - atleast you're not in the US, where the most common measuring tapes are _inch-only._
YES!
The answer to the question why the US still uses imperial… money!
Just think about the cost to replace ALL trafficsigns with distance and speed in the whole US… insane! For example 1 trafficsign to replace $250,-..?…. ( production and replacement)
I love to watch Americans react to this video. Dude did an awesome job and greatly portrayed the problem with Imperial system. Although i can imagine as a European that changing a measurement system in a country that is made from different states with such a big number of residents would be a government nightmare... Still i think that as a united species we NEED to use one measuring system. There is also a topic of a temperature measurement which also is better in Celcius. Idk know how the hell you're not using this...
Also when i watch some nice food recipe videos on YT and see all those cups, ounces and other attrocities im just like "nah brah i can starve to death thank you"
Just change one part of the measurement system at a time, so year 1 - pints and gallons become bushels in texas, year 2 bushels become litres in texas, pints and gallons become bushels in ohio, miles become furlongs in texas, year 3 furlongs become centimetres in texas, miles become furlongs in Ohio, pints and gallons become bushels in hawaii , bushels become millilitres in ohio. You see, not one instant of Federal Regulation is needed, every state can pick its own conversion rules and units, there are so many to choose from.
The US doesn't actually use the "imperial" system. The imperial system was formalized in the 1820's; the US would scarcely have signed on to such a system (there had been some unpleasantness with the Brits about 10 years before). The imperial system was devised by people who used "12 pence to the shilling, 20 shillings to the pound ... and then there were odd things like guineas which are 21 shillings, but were no longer minted after 1814, though they remained in accounting terminology. ) The US uses the much older "common" measure ("Queen Anne's"). However, Jefferson was in favor of the metric (among others). Metric seems to be particularly common for global sales ... so John Deere would use mostly metric. I think Caterpillar is sort of a holdout, but that seems more tied to the (massive) expense of re-tooling. Having to make completely new castings for (say) just the multiple forms of pistons used on their heavy equipment ... Still, it gives some of their competitors (Hitachi?) an advantage, so it seems like something they will have to do. I think it will take longer before peaches (say) are no longer sold by the pound at the supermarket. Well, just a thought.

Fyi…. There are no conversions involved in the bridge example. It is just measuring distance. 12” in 1’ and 5280’ in a mile. So the number of inches in a mile is not a conversion, it is a calculation.
39,37 inches in 1 meter is not conversation, it is a calculation ;)
Metric is far better.
America doesn't use the Imperial system it uses a variation of it. Look up the conversion between a UK quart, a US dry quart and a US wet quart and you will get three different figures. the UK one is the Imperial one. Fluid ounces and gallons are also different between the US and UK.

The US's imperial system is based on the old Queen Anne imperial system. British imperial was later reformulated in terms of metric units, and by a strike of luck, our pints grew significantly larger.
@Robert Claeson that's the best bit 👌
The funny thing is, that they use metrics for they money. If they love imperial that much, why don't they use the old english pound system. I mean that together with the fact that taxes are not included on the prices you see, that should be a lot of fun 😄😄
It is still BS anyway
Most annoying part as engineer is that imperial uses fractions instead of decimals. What the heck is 35/64 of an inch. just say it's 0,546875 inches. NOOO we use decimals like 0,55 inches, that's too confusing. unless it is more accurate measurement than fraction of 64, then we might just use decimals. Oh an in adition we can mix and match 35/64 inches with tolerance of 0,05 inches! Amazing.
You need a guide book to use imperial metrics and converting metric to imperial in a way that it makes sense in fractions forces to make measurement changes. Cant just convert with factor.
metric system works on four numbers mostly in base. 1, 10, 100 and 1000
The reason the imperial system is such a mess is how it came about. It was based on purely human concerns. An ounce, for instance, might be defined as 'the weight of an egg'. Problem is, of course, that eggs vary in weight, and so what the _accepted_ weight of an ounce is would vary from place to place. So you'd be in one town and they'd have weights they specifically use for measuring that are what they call 'an ounce', and then one town over the 'ounce' would be based on a similar but slightly different weight. The 'foot' was originally defined as the size of the king's foot, which would, of course, vary from kingdom to kingdom and also every time a new king took over. Probably not by much, but small differences add up.
Eventually merchants got sick of this because it caused headaches for them and pressured kings and such to 'standardize' the system. A foot became some fixed length, an ounce a fixed weight, and so on. At first this held within a country, and eventually got spread when England entered it's Empire phase and forced all the places they invaded to use it, too, which facilitated trade. And yet the pound would be likewise based on something like that and then they'd work out what the conversion was between ounces and pounds. Each individual method of measuring the same quantity, each _unit_ of measure, was arrived at independently of the others with no consideration for the other units being used, and conversion factors were just a matter of calculation, even after they were standardized.
Metric came along at one point because they recognized the silliness of a system that operated this way. They based it on base-10 counting since that was the most common where they were. However notice that there's still 'magic numbers' involved, (like the meter being defined by how far light goes in 1 over 299,792,458 seconds. Why that number? Why 299,792,458? ... Because that'll make it match what a meter is based on badly measuring half the circumference of the Earth and dividing by 10,000 (which is where they got the meter in the first place). Wouldn't it make more sense to start over, have a new system, and make whatever we call the base unit be the distance light travels in 1/100,000,000 seconds? Much nicer! One reason that this doesn't matter, though, is that you don't need to memorize that number, 299,792,458, to _use_ metric. The definition doesn't much matter. Unlike the imperial system where in order to use it you _do_ have to memorize the number of inches in a foot, feet in a yard, yards in a mile, and so on.
Another issue is why we're using base-10. If we were going to restart, make a new measurement system, let's change the number system while we're at it. With the way computing works, it would seem to make sense to switch to base-16. Right now when we look at computer values and code, it seems like a foreign language. Computer storage looks like this: 01 23 A4 2B 44. That's because it's in hexadecimal (base-16). But because we don't _use_ base-16 in our everyday lives, we can't really 'read' what that's saying. If we wrote the same thing out in decimal, it would read 001 035 164 043 058. You can _read_ that just fine, you know _exactly_ what that string of numbers is, even if you don't know exactly what it _means,_ and you can even combine them. You can read 035164 as a number and understand it, but try that with 23A4. Even if you converted each segment you can't easily combine them. If we could read hexadecimal as easily as we currently read decimal, that'd be a superpower for dealing with computers. Given how much computers run our lives these days, that might be pretty useful!
Or perhaps we could go back to the Roman idea which has some serious utility. Go with base-12 counting. The nice thing about base-12 is that has several useful divisions that are extremely common with pretty much every human thing we do. When you look at 10, it's evenly divisible by 2 and 5... and that's it. You can easily get to 'half' of a quantity, but if you want 'a third' or 'a quarter', both of which are really common things to need, the math gets harder because you start needing decimal places and so on. But what about 12? Evenly divisible by 2 _and_ 3 _and_ 4, not five but also by 6. Those are some pretty common ways that we split things. In fact 2, 3, and 4 are the most likely ways we'll ever split anything (two people, three people, four). Six is pretty common, too.
On the other hand, back to base-16, you can evenly divide that by 2, 4, and 8, also rather common divisions that show up pretty frequently. In both cases you can get a length unit that is _close to_ the current metric one (I don't know about the others, to be honest) while being easy to remember. Sticking with base-16 (which I think is the better idea), The number '10,000,000' in base-16 is, in decimal, 268,435,456. That's pretty close to 299,792,458. It would mean the unit of length would be 89.5% of the size of the current length, but we could adapt. Of course, this presumes the 'second' remains the same, but you get the idea, we can pick a 'magic number' that is a power of the base of the system for the measurement, which would make even remembering _those_ values easy.
I _also_ think we need to get a metric-style definition of time. So pick one unit (second, minute, hour, realistically something entirely new), and make the other units a base-power multiple of that. In decimal we could, for instance, have seconds, decaseconds, and centaseconds, each being a multple of 10 difference, so ten seconds in a decasecond, 10 decaseconds in a centasecond. No conversion. The one thing that would seem to be 'bad' about this is that a 'day' won't be some nice number. It won't be '24 hours', for instance, but might end up as 13 centaseconds 9 decaseconds 12 seconds. Which seems cumbersome. _However,_ there's a utility to be found here. Right now we live on just one planet, Earth, which is not a great strategy for long-term survival. We want to get off this planet. But if we do, _no other planet_ is going to have a day that's _exactly_ the same length as our own. Yet imagine how easy adapting will be if we understand when we get to a new planet or whatever that the 'day' (maybe we'd call it a 'rotation' by then) is just a different number of centaseconds. "Hey, we're on Mars. The day here isn't 13 centaseconds, 9 decaseconds, it's 13 centaseconds 12 decaseconds." Not really that much harder to adapt to than time-zone change. It'd future-proof us for when (if) we leave Earth and set up shop elsewhere.
In everyday life you can use any system, it’s not so important. But everything changes as soon as you are faced with engineering calculations. Here the advantages of the metric system are undeniable. At the end of the video, it will be noted that now the standards or benchmarks of weight or length are not physical objects made of metal, but a long description through formulas linked to eternally constant physical quantities (Planck’s constant, etc. So scientists thought that it would be more reliable than have a metal cube weighing 1 kg (after all, when slightly heated, the metal emits electrons into the atmosphere, and this is a loss of mass, for pure science this is unacceptable, but for everyday life it is acceptable.) Therefore, we decided to describe what a second, meter or kilogram is in terms of eternally constant values from world of physics and no longer make them from metal or anything else. For example, now 1 second is a time interval equal to 9,192,631,770 periods of radiation corresponding to the transition between two ultrafine energy levels of the ground state of a cesium-133 atom at rest at 0 K .

It's simple , just decide or multiple by the base of 10 factors ( water ever it's called )
I grew up and live in Germany, so I´m used to the metric system.
There was however one big change of units during my livespan: the switch from Deutsche Mark as a currency to Euros.
The switch was done about 30 years ago, with an overlap of three months, where both currencies were valid, after which the Deutsche Mark was phased out.
Near the end of those three months, I found a 20 DM bill in a jacket I had not worn for some time and bought some fast food . The cashier really seemed to struggle for amoment, almost giving me a look he would give someone trying to pay with bills from the game Monopoly.
On the other hand, despite 30 years between the switch and today, many Germans (including me) tend to convert the price of certain goods back to Deutsche Marks, just to get a feeling if the price is appropriate or not. Due to infaltion, most of the times, the answer of course is a loud: "NO!!!!!"
Dispite the advantages the Euro brings (travelling between countries in the EU without having to bother getting some cash in the other nations currency, or when trading goods and money transfer), it is still rather unpopular, since almost any european citizen has a feeling that they were better of with their former currency (as alredy mentioned: inflation plays a big part in this).
Long story short: The big project of agreeing on a very straight forward system of base units has already happend aroung the world, only America, Lyberia and Myanmar are refusing / used to refuse to switch. And to a certain degree, I understand why. Ok, inflation won´t play a role in the system of units. ;)
But having grown accustomed to a set of units and converting to a different one is kind of like starting to use another language completely - and it is not the language you think in, you dream in. Despite the essential advantages of the easy conversions, the Americans will most likely think of a distance in miles, to have an idea, a gut feeling for how long it will take to got there by car, how much fuel it will take to get there, how much it will cost. If given the distance in kilometers, in the beginning, any one will do the maths to be certain, even if they first calculated based on metric units to get used to metric units. Just to be certain. And this gut feeling, this double checking will remain in the every day life for at least a whole generation, if not longer.
Still, getting rid of conversion (and related errors) and misunderstandings, I think it is worth the efford.
America is changing slowly, buying foreign cars and Austrian 9 mm pistols, uses a military rifle of 1 m length using 5,56 mm bullets. You see, the change is on the way.

12 inches = 1 foot: 3 feet = 1 yard: 22 yards = 1 chain: 10 chains = 1 furlong: 8 furlongs = 1 mile shows how insidiously convoluted the imperial system is.
bruh! say whaaa?
there is ton and tonne, one is 2000 and the other is 2240
@@b1ca Ton is imperial, tonne is metric. I tonne = 1,000 kilograms.
1 tonne is 1000 kg. 1 litre of water is 1 kg. 100 cm is 10 decimeter is 1 meter. 1 kilometer is 1000 meters. 1 joule is the energy needed to lift the temperature of 1 gram of water by 1 kelvin or celcius. 1 watt is 1 joule per second. The only thing that defies logic is the clock with ancient 12/24 hours and 60 minutes and 60 seconds units.
@@b1ca Long ton and short ton, tonne = 1000kg
The only people that ask that question "is the metric system better?" Are Americans, the rest of the world uses the metric system and already know it is far better.
0:11 No, the UK uses a hodgepodge mix of the two.
Anyone that has taken even high school science knows that metric makes more sense. And if you've done any college level science, you laugh at those who still insist on a system designed by those who marry their cousins.
5:15 - That's NOT video of the "Gimli Glider" landing. The Air Canada plane landed intact and took off after being refueled. The abandoned air field mentioned was a military airstrip turned into a racetrack, and there was an event that day. Everyone goes racing with fire extinguishers, so there were plenty of rescuers and no injuries.
9:00 - Why doesn't yankland change? Because of the arrogant assumption that it "knows better than everyone". It's also why the yanks refuse socialized medicine, safety regulations, representative government (no, you don't have one), etc.
11:38 - Caesium is used because it's the only atoms that constantly vibrate the same number of times per second.
Without watching the video, the answer to your question is: Yes
Americans don’t even use their own units, I met several guys who measure distance in football fields lol
The reason that it doesn’t change completely is that the government gets too much push back from its citizens to make such a huge change. Australia did it in 1966 and it was relatively easy. It takes a lot of planning and of course there were objections, but once implemented it was easy to adapt. Mind you I still think of height in feet and inches to imagine how tall someone is. But a metre is about 3” longer than a yard so it is easy to have a rough idea.
I can understand the force of habit... and personally I think: hey, people can quit smoking. Which is addictive, psychologically and physically. So why can't they stop to "think" in feet and inches?
Yes, habit... and no repercussions.
But I seriously wonder why someone would give their height in "a few of these units, and a few of those units".
Unified decimal systems are just so much more convenient.
If you work in science or engineering metric makes the most sense. Britain uses a mix of metric and Imperial depending on the context. Beer, plumbing, pressure, measures of energy from vaporous gas, rail gauges and office space work well with British units but for nearly everything else metric rules.
Short answer: yes. It is actually better. Otherwise, the US government, military and the scientists wouldn't use it. The USA government twice accepted a Law to enforce the Metric system in America.
They only use it during months with an R.
When I first started work in 1971, I had been brought up thinking Imperial and to change was a bit of a struggle. However once I got over it, to add two imperial measurements is more complicated.
1 3/8
+ 2 1/4
=???
You have to bring the measurement to the lowest common denominator
1 3/8
+ 2 2/8
= 3 5/8
Working conversions
1 3/8 = 0.03493 which is approximately 35mm
2 1/4 = 0.05715 which is approximately 57mm
so adding these two numbers become easy 35 + 57 = 92mm easy peasy
All that being said, I still use mileper gallon to understand if my car has a good petrol comsumption and although I use meters with work, I talk about miles when talking about distance between towns or miles per hour when talking speed. My brain has a better visual on those rates for me to comprehend the concept.
Ohh well you can't have it all. lol
And that's why we in Europe asked ourselves in middle-school, why do we need to learn mixed numbers when nobody is using them? 😏
By the way, we calculate petrol comsumption in litres per kilometre (usually in hundreds of kilometres), not miles per gallon. It's the other way round!
The US military use metric, because all other NATO countries are metric.
sure ?
@@couvertgerard7742pretty sure.
@@jtommygun It must be complicated for the military to constantly switch from one system to another! For example, the capacity of the tanks is in liters or gallons? Are the times between 0 and 24 or with AM PM?
@@couvertgerard7742 yup, you see all the time in the movies something like, "we meet at zero eight hundred hours" 0800 is eight o'clock in the morning, the time is always in 24 hour format, without forgeting the leading zero when is necesary, or "we are five klicks from the road", klick is jargon for kilometers. etc.
America was going to convert to metric.... but pulled out last minute !!! Need to stand out or something I guess
or most likely took a sadistic Grifterian delight in making everyday life more complicated than necessary for the rest of the world when they have to deal with the quirks of the United States of America.
But wait, there is more. There are more units that sound the same but mean different sizes. Gallon in the UK and gallon in the US, anyone? And then go to very "logical" ounces etc.
Gee I hope that the new submarines that Australia will get are all metric.
The radiation will be.
3 countries are uysing imperial system but most Americans now think there are 4. USA, Myanmar, Liberia and the 4th - Europe. I`am not kidding I watch Jay Leno`s street interviews
in the first half minute, the video starts already with missing knowledge about which system the usa use ...
although many people call it "imperial", it's different, there used to be several imperial systems,
and the current system is legally defined by conversion factors from the metric system and SI units.
Money is metric
Just like your fingers
explains why it slips through
and rarely lingers.
But we British still have not let go of imperial. We hold on to bits of it with white knuckles, like our Pint of beer, but we have no hangups with grabbing a litre of milk at the corner shop. Most people describe their hight in feet/ inches. And road speeds and distances are still in MPH and Miles.
the only thing Brits dont hold tight is the EU, i guess we use to much metric, which came from the French and the Brits are just jealous about it!
The answer is Yes, most of the world uses the metric system, y'all need to get with the times.
it's easier to use metric and kilo, u just have to put some '','' to convert . don't need any paper. love your videos, big hug from Portugal
Its crazy to think that the french revolution created the metric system but in the americsn revolution americans kept the literally "imperial" british system, its like wtf bro
So if a 1 cubic metre of water weights 1 metric ton (t) or 1000 litres (l). 1 litre of water weights 1 kilogram (KG). So if I'm going shopping and buy 5 l Milk and 2l of soft drink I'm carrying about 7 kg in my bag. Simple.
not if you are a US Karen, the souls of the poor employees weight much more!
Just for puntualization: 1 litre of water is 1 Kg, but 1 litre of some other liquid is not. It depends on the density of course. But this is not a measuring system issue, it's just physics
@Gianninnn You're right. What I said doesn't comply with the AS 1100 it should have had no punctuation and all in upper case except for the abbreviations accepted by the standard in lower case. Yes, some liquids do not have the same density as water.
How can you determine time like that if time is relative. Just asking
It was stated in the video, just like all the other basic units its definition is based on a scienetific observation inserted with the rest into a comprehensive whole.
If i remember correctly the ceasium 133 isotope was used because its "vibration"-fequency remains very stable even if there is interference from outside.
So time as any other basic unit stays "relative" in reality, but theory needs to be backed up by useful facts, the error of some ceasium 133 atomic clocks is somewhere at 1 second in a bunch of million years, more accurate "clocks" are beeing invented.
@@VJ-tn4yr so if you take c133 close to speed of light does it vibrate slover frequency
@@jukopliut You'd still need to operate a atomic clock as a whole body at light speed, because of static speed and no velocity there should still be a unchanged condition regarding the measuring itself.
As for fringe effects etc., for example the theory that the perception of time would slow the faster you move, ask a physicist... or ChatGPT...
@@jukopliut That's not how it works. It "vibrates slower" from the point of view of someone in a different frame of reference (i.e., the observer to whom it is moving "close to the speed of light"), but just the same to someone travelling alongside it. You can only properly measure things in the right reference frame.
a whole 3 washing machine wide has opened. american will use anything but metric system to describe things :D. sry for a joke :D love your reaction on football fans and i guess yt algorithm offer me this video. plus it was great. we in europe learn some stuff in difference between system and this was even better. thanks man
9:11 another name for the metric system is the International System
Not really. System International (S.I.) is related to, but not the same as, the Metric System.
@GH1618 I don't know why you think that....
The International System of Units (SI), commonly known as the metric system, is the international standard for measurement. The International Treaty of the Meter was signed in Paris on May 20, 1875 by seventeen countries, including the United States
Just about the whole world uses the metric system bar the US 😂
Oké,I feel stupid
I like to watch old car videos. They talk about how much miles per gallon. I dont know how good or worse it is🤣. Just say how much kilometrs per liter.
Would be more or less kiliometers per litre. But we use the opposite (L/100 km)
All you need to know in the matrix System is how to properly shift a point from left to right or vice versa.not that hard. For all who love fun videos:Happy phun time farm: the metric system is bulldoggery is great!!!❤
It doesn't make sense to ask which is best because both do the same jobs. However which is simpler? Well clearly metric is far simpler as it uses factors that make doing the sums far easier. Now I grew up in the UK where both systems were common and to this day most people measure their own height in feet and inches, their weight in stones and pounds, and the roads are measured in miles and speeds in miles per hour. But ask the scientists and engineers in the UK and it's almost certain they will talk in terms of metres, centimetres, kilograms, kilometres and kilometres per hour. Having two systems is usually blamed on the older people not being used to the metric system, but then now I am one of the older people and see people my age who were educated in metric still reverting to imperial.
Now I am living in the Netherlands and here everything is metric but it does have a legacy and very occasionally you encounter that. For example at the market stall you can order fruit and veg in pounds (actually pond) which is now 500 grams. To give you an idea of just how confusing the weights and measurement system used to be, in the 1820s we switched to metric but before that there was not just one single definition of pond, we had at least 9 different regional definitions of pond which varied from 275 grams up to 497.8 grams. So introducing a standard of 500g made perfect sense when metric was introduced.
Then we have another old measurement that is not actually used and that is the duim (literally thumb) and that is where the rough length inch comes from (the top part of the thumb back to the joint). The phrase duimstok (thumb stick) is a reference to a type of wooden folding measuring device that you might have seen used by certain professions but has largely been replaced by a tape measure. But interestingly the phrase "rule of thumb" comes from the use of this vague measurement.
Easier to use = better.
Short answer: Yes it is!
Not even a contest xD
