What is a Millimeter and a Meter?
The millimeter is a unit of length in the metric system equal to one-thousandth of a meter (1/1000 m) or one-tenth of a centimeter (1/10 cm). It is used for very precise measurements.
The meter is the base unit of length in the International System of Units (SI). It is defined as the distance traveled by light in a vacuum in 1/299,792,458 of a second. It forms the basis for other metric length units.
Note: The Millimeter is part of the metric (SI) system, primarily used globally in science and trade. The Meter belongs to the metric (SI) system.
History of the Millimeter and Meter
Defined as a subunit of the meter within the original metric system, the millimeter provides a standard unit for fine measurements required in science, engineering, and manufacturing.
Originally defined in 1793 by the French Academy of Sciences as one ten-millionth of the distance from the equator to the North Pole along a meridian. Later definitions involved prototype bars (platinum-iridium) and wavelengths of krypton-86 radiation before the current definition based on the speed of light was adopted in 1983.
