Meters

The metre is the SI base unit of length, defined since 1983 as the distance light travels in a vacuum in exactly 1/299,792,458 of a second, anchoring its definition to a universal physical constant rather than any material artefact. Introduced by the French Academy of Sciences in 1791 as one ten-millionth of the distance from the equator to the North Pole, the metre became the cornerstone of the metric system and is today the official unit of length in every country that has adopted SI. In science and engineering, virtually all derived units of length, area, volume, and many physical quantities are expressed in terms of the metre.

Millimeters

The millimetre is a unit of length equal to one thousandth of a metre (10⁻³ m), derived using the SI prefix milli- (from Latin mille, thousand). It is the standard unit for precision measurements in engineering, manufacturing, and medicine, where tolerances are routinely specified to the nearest millimetre or fraction thereof. In meteorology, rainfall is universally measured in millimetres, where 1 mm of rainfall corresponds to 1 litre of water per square metre of surface area.
