Metric Distance Conversion with Whole Number Values

Metric units are easy to work with, since they are all multiples of ten (or a hundred, or one-tenth, and so on) of each other. You can convert between the various units of different sizes by merely moving the decimal point the correct number of places.

The most common metric measurements for length are the millimeter, the centimeters, the meter, and the kilometer.
