Question

13g= how many cg
0.6 m = how many mm
5.9 l = how many cL
49.74 W = how many mW

Answer 1

1 gram = 100 centigrams. 1 meter = 1000 millimeters. 1 liter = 100 centiliters. 1 Watt = 1000 milliWatts.

Answer 2

So I multiply all of them?

Answer 3

Taking the first question, (m grams) [(100 centigrams) / (1 gram)] = 100m centigrams. Yes, you multiply, but you should look at this last equation as a model for cancelling units. The second factor on the left is in essence multiplying by "1" as it is an identity, and when you multiply by the multiplicative identity, or 1, you preserve the original answer. You are basically just converting units, which factor out since "grams" is in the numerator and the denominator.

Answer 4

So if it is from small to big, then multiply. Then if it is big to small, divide?

Answer 5

You could think of it that way, but I don't suggest you do that. You will lose the logic and the methodolgy and you run the risk of not being able to repeat or demonstrate this to either yourself or others in the future. In other words, your understanding will be shaky. Better to go over my equation until it sinks in deep.

Answer 6

Ok.
