- This video focuses on how to convert units with scientific notation. I work through three examples involving converting from one unit of measurement to another. Some of the units involved in this video involve picometers, centimeters, nanometers, etc.

So helpful. Helped me learn in 5 minutes what I was not taught in 4 months by my chem teacher. Thank you!
Glad it helped! This is a tricky topic to teach! Sometimes you just have to see another approach.
this was really helpful, our teacher didn’t explain the process and thus most of our class got confused, ty
I am glad you were able to learn from the video! This is definitely a tricky concept to teach. You need strong math for science, especially in physics and chemistry!
THANK YOU! You did a better job explaining this than my professor did! :)
This topic is tricky to teach for sure! I am glad the video made sense!
Best video to learn conversion. Loved it ❤️
@thestreamer6825 I'm glad you think so! I hope your school year is going well!
May god preserve you, broken down a topic into 5 min, which my profs didnt manage to do in 3 months!
I am glad this video was easy to follow! I do my best to make it easy to understand.
There are so many things on my chem exam tmrw, but this checks off one less thing I need to review for it, Thanks!
How did the test go?!
@@vinteachesmath I got a 68 unfortunately.
Thanks a lot 💖
I forgot the scientific notation method after not using it from a lot of time haha.
I guess you gotta revise this stuff from time to time 😁
You're welcome 😊
It is very easy to forget the techniques when you do not use them for a while. If I had to take one of my old college math finals, I do not think I would be able to remember much!
Thanks for supporting the channel.

Thank you so much for this explanation! Makes perfect sense now 👏
Thank you so much for this explanation! Makes perfect sense now 👏
Tysm it was so helpful it helped me alot 😭
Very well explained! ❤
Glad it helped! I hope your school year is going well!
the way you teach is really simple to understand
thanks a lott
Can I ask why at the third case the result was 1.5 • 10 in the power of 16? Shouldn’t it be 10 in the power of -8?
I’m confused
10^4 ÷ 10^12 = 10^(4 - (-12)) = 10^16
10^4×10^-12 = 10^(4 + (-12)) = 10^-8
In the third example, I was dividing those exponential terms so we subtract the powers.
Your answer would be good if we multiplied.
@@vinteachesmath oh, now I understand. Thank you very much ❤️
I am confused, the last one. Why is the answer 10 to the 16th power and not 10 to the negative 8th?
We are dividing 10^4 / 10^-12, so we use the algebraic property a^b / a^c = a^ b - c. Your answer would be correct if you were multiplying 10^4 x 10^ - 12, then you would add the exponents to get 10 ^ -8. (Note: a^b x a^c = a^ b + c)
thanks a lot, I understood everything now!
You are welcome!
thanks a lot, I understood everything now!
Thank you soo much, I was having this silly confusion for years. but under 5 min you solved it which my teachers cant. thankyou god bless
I am glad it finally clicked! Sometimes I have to hear it a few different ways before it clicks! I am glad that this video did it!
Thanks a lot! It really helped me
Glad it helped! I hope your school year is going well!
u a real one fr🔥
I'm happy to help!! I hope your school year is going well!
This helps but how would I do this with exponents on the units of measurement like km^2 to mm^2 or mm^3 to m^3?
You would need to square the whole conversion, for example 1 ft ^2 = (12in)^2 = 12 in x 12 in = 144 in^2

See im confused. In number 2 how did you get 10^-2?
.053 = 5.3×10^-2
I converted the original number to scientific notation. Also the prefix for centi is c which equals 10^-2
he changed it into scientific notation and when you move to the right to get the s.n the power is negative!

@@V_ennmath but when he converted 60 to micro, it became 6 x 10¹, but for 0.053 m, it became 5.3 x 10-². How came it became negative?
6*10^1 is right because 60 is a number greater than one. The six could also be written as 6.0*10^1. You are moving it one place to the left. This is the reason why the exponent is positive. .053 is a number less than one so the exponent is negative. You are trying to move the decimal place so it is in front of the two numbers of 5 and 3. This means you have to move the decimal place two units to the right in order to achieve that. Which is why it is 5.3*10^-2
Thankssss so much but what if its 25km/h to m/s? Is the process the same?
Yes, it is the same concept! You would also need to convert hrs to seconds using the fact that 1 hr = 60 min and 1 min = 60 sec.
Why did you conver 15 to 1.5 and 0.53 to 5.3 please explain what is this called?
It's called scientific notation
Thank you sooo much
Happy to help!
Thank you sooo much
watching this in 2024 Feb 16 and m soo thankful I came across this video
I'm glad the video helped! Are you watching this to help with a science or math class?
Im failing exam its tmr dang it
How did it go?!
@@vinteachesmath i manged to do 3 and i failed 2 thanks still
0.000000000135T into M
Rewrite your expression as
1.35×10^-10 T
Note: T=10^12 and M = 10^6, so
(M/10^6 = 1). Now we substitute:
1.35×10^-10 × 10^12 × (M/10^6) = 1.35×10^-4 M
