The metric system is an international structure of measurement used by most of the world as the primary system of measurement. Most people apply this form of measurement; however, it is especially useful to those in specific fields, including astronomy, engineering, physics, and other sciences. A meter is a base unit for the measurement of length modified by the international system of units.
The prefixes for the measure of smaller units include centimeter, which means 100, and millimeter means 1,000. Both centimeter and millimeter are part of the standard system of measurement that is used today by scientists and the average person. The International System of Units also determines these lengths. A millimeter is a unit of measure which is equal to one-thousandth of a meter.
A meter has 1,000 millimeters. It is also comparable to 1,000 micrometers. There are 100 centimeters in a meter, which is nearly the width of an adult fingernail. Centimeters are used in sewing to obtain proper measurements. It is also the measurement used to calculate snowfall. The centimeter is ten times larger than a millimeter.
