I erroneously stated that 3 centimeters equals 300 millimeters!!! I an noted the video with a poll comment that lets you decide between a senior moment or a brain fart as the root cause for the error. Check it out at the 20:23 mark, Marc
I make this error all the time as an old geezer raised in the imperial system. When I see "centi" I think 100, not 10. I find the centimeter in the shop almost useless and confusing... put everything in millimeters and I have no trouble going from metric to imperial (as far as making a quick estimation). I know that the inch is defined by the meter exactly and by memorizing 4 conversions, Bob's your uncle. 1"=25.4mm exactly, 5"=127mm exactly, 12"~300mm, and 0.03937"~1mm very nearly (as close as you can measure in the shop...and this also tells you that 1 meter is 39.37" or 39 3/8" within 0.005"). As others have noted all German mechanical drawings are in millimeters. In Austrailia mechanical drawings and building drawings are all in millimeters.
We learn the nost from the senior errors, when theyre noticed and we say to ourselves "what the hell is he talking about" is when we learn not to repeat those mistakes. Thanks for the education, what i owe you for tuition? Haha
Marc, I am quite full with gratitude. I am a 64-year old man. Would that more men in other trades were inclined to such tutoring. Then it wouldn’t be as hard for such as I to transition from unskilled to skilled labor. May God bless you in the way He chooses, appropriate to your needs. I say again for what it’s worth: Thanks!
Hi! Thank you for taking the time to write and for letting me know that the videos are helpful. It's nice to know that my little retirement project is appreciated. Thanks again, Marc
Nice to see you back with this interesting introduction into metrology. One little correction from a "metric guy": 3 cm equals 30 mm (not 300 mm as you probably misspoke). In Germany the mm is mostly used as the "base unit" in machine shops working with metals whereas the "wood guys" like carpenters or joiners traditionally use the cm. Looking forward to watch the next episode Harald
Hi Harald! I corrected the oops with a poll annotation that lets you choose the cause of the error. A brain fart or a senior moment. Thanks for letting me know, Marc
Since I cannot hope to ever actually learn from you directly in a classroom, this is definitely the next best thing. You provide a fantastic service to all of us wishing to increase our knowledge and skill. Thank you so much for taking the time!
Love your videos qnd the education, your take on how things are done. Videos are great as is, but a directional microphone or shirt clip mic might be beneficial to get rid of echo or reverberation. Would make is easier to focus on what youre saying.
Some very good points made in that vid, Good Sir! As to the 300mm, I attribute that to Canuckistanian aftereffects from being neither here nor there with imperial and metric :) . But then of course, there are also beauties like the Imperial US and imperial UK gallons and miles being different and what not (no, sorry, canadian cars do not intrinsically have higher mpg than US ones...). On a more serious note, it is quite noteworthy (and disturbing) to see that many people have a very bad concept of numbers and orders of magnitude when they have not experienced them upclose first hand. Probably why you'll see engineering students from our finest universities that will design parts on Solidworks all day long with 15 significant digits and assume that any shop will be able to machine them to much better than a hundredth of an thou at will... That's where you are making a worthwhile difference, TLM, and thanks for that!
I really enjoyed watching this video, but I am still confused about why it raining today hopefully you will get onto the weather in future videos. Best Regards Chris
Thank you, I’m enjoying this video and will watch the series. Only thing I would like to say is METRIC! why won’t a small percentage of the world (America) move to such a logical measurement system? We’re not perfect with it here in the UK, mainly pints and miles 😢 but meter, centimetres, mm and 0.1, 0.01, 0.02 etc is so much easier than 17/32 nds and thousands. Cheers At 20.30 3cm is 30 mm not 300 😀
Mother Nature does not suggest any standard length of measure. For example, the meter was arbitrarily defined as one ten-millionth of the distance from the Equator to the North Pole.
Since I never use the Centimeter as a unit of measure, I would never have caught that error, CM’s just ruin my day! I’m slowly getting better at metric conversions. But don’t ask me how many thousandths are in .1 mm.
I've only recently started my channel so you will understand the smile when I hear a silly mistake, 3 cm = 300 mm. I am a soon to retire EE, my shop is not complete but I have a small lathe, mill and I'm learning much from all you gray beard guys. I have enjoyed your channel and look forward to the lessons...

I see the flattering comments. I'm sure it's true for most that commented. For me I've heard of watching paint dry buuuut this is like hearing it dry!!! I just can't take it. To much analogy instead of just down to the grits.
I produce the videos for novice machinists. I think that the videos are helpful for those who are just starting out and want to understand as much as possible in order to increase their confidence before starting to machine. For others however, as the kids say, it's just TMI. Thanks for watching and for taking the time to write, Marc.

The mistakes are easier to remember than the sucess. Human mind.
Aceroadholder the centimetre is not a "preferred" unit in the current metric system, so you can legitimately ignore it.

Fuck metric!
Thank you for all of your videos, Sir.
Hated metric measuring tools , never used . When dimensions were in metric we converted to inches , to old to set in ways to ever change
Since I cannot hope to ever actually learn from you directly in a classroom, this is definitely the next best thing. You provide a fantastic service to all of us wishing to increase our knowledge and skill. Thank you so much for taking the time!
Great and informative videos ! But, Thank goodness for playback speed settings. Thanks Marc ! !

I love learning new things Thanks
Dear Marc, thank you very much
Lesson: 8
Good one Marc. We all make those errors.
nice to see your again with nice topic sir...
Thank you!
Thanks! Great videos!
Thanks

At 20.30 3cm is 30 mm not 300 😀
i likee this guy very much
the standard meter in Paris is not bronze.
90% Platinum, 10% Iridium.
Correct. It's useless. No one has relied on that relic for a loooong time.
and if memory serves made by Johnson Matthey in England.
Hmm, 3cm = 30mm.
Good intro. Now I know what a cubit is.
I fixed the problem with a poll annotation, at 20:23 you get to choose between a brain fart or a senior moment. Thanks for the heads up, Marc
about 12 minutes in: between 4.995 and 5.500, i cannot tolerate this!
Nice, but 3 cm = 30 mm instead of 300

So why don't we have a wavelength based measurement?

Thank you! Someone is finally going to explain finish. That's why I subscribed.
