UNITS OF MASS (WEIGHT). Four major metric units of mass are:
milligram (mg) -- 1/1,000 gram
kilogram (kg) -- 1,000 grams
metric ton -- 1,000 kg or 1 megagram
The milligram is so light (about the weight of a grain of sugar) that it is
seldom used except in medicine and other scientific areas. The
megagram or metric ton (about 2205 pounds) is used for heavy things.
The metric ton is about 10 percent heavier than the U.S. short ton (2,000
pounds), but a little lighter than the U.S. long ton (2,240 pounds).
