Please provide values below to convert meter [m] to millimeter [mm], or vice versa.
Meter
Definition: The meter (symbol: m) is the base unit of length in the International System of Units (SI). It is currently defined as the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second.
History/origin: The meter was originally defined in 1799 as one ten-millionth of the distance from the equator to the North Pole along a meridian. Over time, with advancements in science, the definition has been refined for increased precision. The current definition, based on the speed of light, was adopted in 1983.
Current use: The meter is used worldwide in nearly all fields of science, engineering, and daily life. It is the standard unit of length in most of the world.
Millimeter
Definition: A millimeter (symbol: mm) is a unit of length in the metric system. It is defined as one thousandth of a meter.
History/origin: The millimeter is derived from the meter, the base unit of length in the International System of Units (SI). The prefix "milli" indicates a factor of one thousandth (10⁻³).
Current use: Millimeters are used worldwide in various applications where precision is required, including engineering, manufacturing, and construction. They are also commonly used in everyday measurements for small objects.
