1 Foot = 12 Inch
Key Formulas
Centimeter → Inch
in = cm × 0.393701Kilometer → Mile
mi = km × 0.621371Foot → Meter
m = ft × 0.3048Inch → Centimeter
cm = in × 2.54Formula
in = ft × (0.3048 / 0.0254)Converting feet to inches multiplies by 0.3048 / 0.0254, which gives 12 inches per foot. Both units are international customary units: 1 ft is 0.3048 m and 1 in is 0.0254 m, so the ratio is a whole number. Carpenters and tailors use it to express a height such as 5 ft 9 in, or 5.75 ft, as 69 in. NIST Handbook 44 lists the inch and foot relationships. The US survey foot is about 2 parts per million longer than the international foot, a gap the NIST revised definitions describe.
