Learn Metric System & Unit Conversions - Dimensional Analysis - Math, Physics, Chemistry - [16]

In this lesson, we will learn about the metric system and unit conversions. First, we will review what a meter is and how a meter relates to a kilometer. The prefix kilo means thousand, so 1 kilometer equals 1000 meters. Next we review the prefix centi, which means 1/100. This means that there are 100 centimeters in a single meter. Finally, we review the prefix milli, which means 1/1000. This means that there are 1000 millimeters in a single meter. With this information, we can now begin to convert between units by setting up a unit conversion table. This is a powerful technique and in fact using unit conversions can be used to solve a great variety of problems in more advanced classes such as physics, chemistry, and engineering. We will convert between metric units and get practice by solving problems.

You helped me understand it more than my professor could. Thank you.

Hi, here is how a learned this (a long time ago). The units are (from left to right): Km, Hm, Dam, m, cm, dm, mm. I just work with the shifting the decimal point to the left or to the right. If I have 100.0m to convert I do this:
Km Hm Dam m dm cm mm
0 1 0 0. 0 0 0

(I keep the excess zeroes in my mind only - written to ilustrate).

To convert to 'cm' I move the decimal point 2 steps to the right: 10000.; to convert to 'Km' I move the decimal point 3 steps to the left: .100. Consider that the decimal point does not occupy a position under a unit of measurement, but it "points" the target unit for you!

Square meter to square Km? Move the decimal point to left by 2 steps each time: 10, 000m2 = 100Dam2 = 1hm2 = 0.01Km2. Also equal to 1, 000, 000dm2.

Volume? Move the decimal point by 3 steps each time, to the right or to the left: 15, 000m3 = 15dam3 = 0.015hm3 = 0.000015Km3 = 15, 000, 000dm3.


Thank you.

I'm Brazilian and your videos have helped me a lot. You are one of the best teachers I will have in my life.

THANK YOU... SIR...!!!
Good review...!!!
Best Teacher...!!!

[Rickelsonnih]

Thank you so much for your dedication and commitment as a S.T.E.M. (based) educator. Like (the late) Professor Clayton Christensen and Salmon Kuhn; I know from where I speak because my son and daughter (and others because we are spreading the word about your very low key-admiral delivery as an educator) continue to benefit from educators of your elk, thank you.

Please take extra precautions to stay safe in these dystopian times); as your dedication and commitment to other are highly valued, especially now during the increasing necessity for distance learning. As you are well aware that in times of uncertainty folks will flock to invest in value.

Perhaps it time that you make a platform move if you have not already done so?

Having to quarantine but still want to keep up with school. Glad I could find such a useful channel to help me out. Cheers mate!

[memorizer]

This is such an amazing channel! I love math and you make it exceptionally easy to! Thanks:)

[antiiilluminatisquad]

Got a chemistry test tommorow, this is all the information I need for it! Thanks!

[kenlangham]

68 and in chemistry thankful for your givens

[ashlieghdavis]

The last time i watch you guys you were 100% but now you are 1000% Love you

[SuongThol]

Thanks for this video really important for me

[UriValdez]

after watching part 1 and part 2 I almost got it, just need to put it into practice.

[karlag]

You are a great teacher! Do you teach Math for Nursing?

[LQVEGA]

Thanks..I would be able to teach my nephews and nieces who are in their high schools now..

[JustFunGeek]

Teach about determinants and metrices please....

[SebastianPerezG]

The nicer of the metric system is that you can convert any mesure, for example liters and grams and meters.

Feel free to learn
Be calm at study
Show enthusiasm at work
Be something, after many things.

I did a little dance to "cancel cancel cancel cancel cancel"

Isn't.it easy TO say 160000cm conver.into metre. For me WOULD say 160000×10 then divide 100. . But for you IS a long WAy

[Andre_XX]

The whole point of the metric system is you just need to move the decimal point left or right. You dont have to do long divisions and multiplications.
