Facts about Millimeter

Basic facts: A millimeter [American spelling] or millimetre [international spelling – symbol: mm] is a unit of length in the SI (International System of Units). The millimeter is equivalent to one-thousandth of a meter and it is defined as the distance traveled by light in 1/299 792 458 000 of a second.

History: The prefix “milli” is one of many metric prefixes. It shows the base unit’s one-thousandth, in this instance, the meter. The current definition is based on the distance traveled by the speed of light in a given amount of time, however, the definition of the meter has changed over time. The relationship between the meter and the millimeter is continuous. Before this definition, the meter was based on the length of a prototype meter bar. The meter has been re-defined based on the changes made to the definition of a second, in 2019.

Use: The millimeters are used to exactly measure the length of small or narrow objects. On a metric ruler or stick it is the smallest unit of length.

Facts about Meter

Basic facts: In Commonwealth spelling – metre, or in American spelling – meter. Metre [symbol: m] comes from the French unit mètre and from the Greek noun “measure”. Meter is the base unit of length and distance in SI [the International System of Units]. It is defined as the distance traveled by light in 1/299 792 458 of a second. The existing definition was adopted in 1983 and changed slightly in 2002 to clarify that the metre is a measure of proper length.

History: Initially, the meter was defined as one ten-millionth of the distance from the equator to the North Pole, in 1793. This changed when the international prototype metre was established as the length of a prototype meter bar [made of an alloy of 90% platinum and 10% iridium] measured at the melting point of ice, in 1793. The meter was again redefined, this time in terms of a certain number of wavelengths of a certain emission line of krypton-86, In 1960. The existing definition of the meter is actually the same as the definition that was adopted in 1983, with slight changes due to the modification in the definition of the second.

Use: The meter is used worldwide (being the SI unit of length) in many applications such as measuring distance, height, length, width, etc. The US is one significant exception in that it mainly uses US customary units like yards, inches, feet, and miles rather than meters in daily use.

How many meters in a mm? 

1 mm is equivalent to 0.001 meters. Use 0.001 as the factor to convert millimeters to meters. Below find some popular millimeters to meters conversion questions:
