About this conversion

The foot (ft) is a unit of length in the imperial / US customary, commonly used for human height in the US and building ceiling heights. The millimeter (mm) belongs to the metric (SI) and is typically found in measurements related to engineering and manufacturing tolerances and bolt and screw dimensions. By definition, one foot is exactly 12 inches, or 0.3048 meters. One millimeter is one thousandth of a meter (0.001 m). The conversion factor between these two units is 304.8: multiplying any value in ft by this number gives the equivalent in mm. For example, 10 ft equals 3048.0000 mm. Going the other direction, 1 mm equals 0.003281 ft. The foot is one of the oldest units of measurement, originally based on the length of a human foot. Its modern definition has been standardized at 0.3048 meters.
