Feet (ft) to Millimeters (mm) Conversion
Feet
The foot is a unit of length equal to exactly 0.3048 metres, defined by the international yard and pound agreement of 1959. Today it is the primary unit of height measurement in the United States and the United Kingdom, and is used in aviation worldwide to express altitude, where flight levels are defined in hundreds of feet. One foot equals 12 inches and one third of a yard.
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.
