The ability to convert from one system of units to another is important in
chemistry. It is often impractical to measure quantities in the standard
meters, kilograms, and seconds, but the laws of science that you learn will
involve constants that are defined in these units. Therefore, you may often
have to convert your measured quantities into different metric units.
The following table lists metric prefixes that come up frequently in
chemistry. Learning these prefixes will help you in the various exercises.
Once you know this, you need to divide one side by the other to obtain a ratio of m to mm:
1 m

1000 mm
If you are converting from millimeters to meters, then this is the proper ratio. It has mm in the denominator, so that it will cancel the units of the quantity that you are converting. For
instance, if you were converting 63 mm, then you would have
63 em

To convert a quantity from meters to millimeters, use the reciprocal ratio:
centi- (c)
