The Language of Mathematics
It is helpful to memorize the prefixes listed
above because they are also used with metric units of weight and capacity.
The most often used metric units of length are kilometers, meters, centimeters,
and millimeters. It is important that you gain a practical understanding of metric
lengths just as you have for the length of an inch, a foot, and a mile. Some examples of
metric lengths are shown below.
