Nautical miles (nmi) to Millimeters (mm) Conversion
Nautical miles
The nautical mile is a unit of length equal to exactly 1,852 metres, adopted internationally in 1929. Unlike most length units, it is geometrically derived: it corresponds to one arcminute (1/60 of a degree) of latitude, making it naturally suited to navigation on the spherical surface of the globe. Speed in nautical miles per hour is expressed in knots.
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.
