Metric Weights and Measures A millimicron is one thousandth of one millionth of one meter. 
Most of the world uses the metric system. The only countries not on this system are the U.S., Myanmar, and Liberia. The metric system is based on 10s. For example, 10 decimeters make a meter (39.37 inches). Units smaller than a meter have Latin prefixes:  Deci means 10; 10 decimeters make a meter.
 Centi means 100; 100 centimeters make a meter.
 Milli means 1,000; 1,000 millimeters make a meter.
Units larger than a meter have Greek prefixes:  Deka means 10; a dekameter is 10 meters.
 Hecto means 100; a hectometer is 100 meters.
 Kilo means 1,000; a kilometer is 1,000 meters.
Helpful Hints Remember: A meter is a little more than a yard. A kilometer is less than a mile. A liter is a little more than a quart. The Metric SystemLengthUnit  Value
