Millimeters to Feet

A millimeter (symbol: mm) is a unit of length in the International System of Units (SI). One millimeter is equal to one-thousandth (1/1,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for 10^-3. Millimeters can be abbreviated as mm; for example, 1 millimeter can be written as 1 mm.

A foot (symbol: ft) is a unit of length in the imperial and US customary systems of measurement. A foot was defined as exactly 0.3048 meters in 1959. One foot contains 12 inches, and one yard is comprised of three feet.The foot is primarily used in the United States, Canada, and the United Kingdom for many everyday applications. In the US, feet and inches are commonly used to measure height, shorter distances, field length (sometimes in the form of yards), etc. Feet are also commonly used to measure altitude (aviation) as well as elevation (such as that of a mountain). The international foot corresponds to human feet with shoe size 13 (UK), 14 (US male), 15.5 (US female), or 46 (EU).

How to convert millimeters to feet

1 millimeter is equal to 0.00328084 feet:

1 mm = (1/304.8) ft = 0.00328084 ft

The distance d in feet (ft) is equal to the distance d in millimeters (mm) divided by 304.8:

d(ft) = d(mm) / 304.8

Example

Convert 20 millimeters to feet:

d(ft) = 20mm / 304.8 = 0.065617ft
