Miles (mi) to Millimeters (mm) Conversion
Miles
The mile is a unit of length with roots in the Roman mille passuum ("thousand paces"), approximately 1,480 metres. The modern international mile, standardised in 1959, is defined as exactly 1,609.344 metres. It remains the primary unit of road distance in the United States, United Kingdom, and a small number of other countries, and is used in aviation for visibility reporting. The statute mile should be distinguished from the nautical mile (1,852 m), used in maritime and aerial navigation worldwide.
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.
