Here we have some unit conversions that we have to do.
00:03
We're going to be working with distance and then with mass.
00:07
However, the values, the 10 to the whatever values, those will stay the same.
00:13
So in the middle we have everything related to one meter.
00:19
So if you're going down from meters to centimeters to millimeters and so forth, you can see that the exponents get larger.
00:29
Therefore, you will have to multiply.
00:33
If you're going the opposite direction from millimeters to centimeters to meters, all the way up to kilometers, here you're just going to have to divide because the values get smaller.
00:44
So let's start with the first one, 42 .3 centimeters.
00:49
We want to go to millimeters.
00:52
So the value on the exponent goes up by one.
00:55
So that means we are going to multiply by 10.
00:59
So 42 .3 centimeters becomes 423 millimeters.
01:06
Now if we were going from millimeters to centimeters, the values are going down.
01:13
So we're going to divide by 10.
01:15
So 0 .023 millimeters becomes 0 .0023 centimeters.
01:22
Now from picometers to meters.
01:25
For these type of conversions, all you have to do is write the 6 .2 and then 10 times the exponent that it matches with.
01:37
So 6 .2 picometers becomes 6 .2 times 10 to the negative 12 meters.
01:45
For micrometers, it's going to be 214 times 10 to the negative 6 meters.
01:54
Now this might seem a little bit confusing because normally you only have one decimal point.
01:59
If you want to make that even further smaller, you can say 2 .14 times 10 to be negative 8 meters.
02:09
Excuse me, i went the wrong way with that.
02:13
It should be negative 4 meters.
02:15
Now 21 kilometers to meters.
02:19
All you have to do is take 21, multiply it by a thousand or 10 to the 3, and you will get meters.
02:28
So this is going to become 21 ,000 meters.
02:33
270 nanometers to kilometers.
02:37
So let's first make a stop off at meters...
