Reference conditions. in: The international yard and pound agreement (1959) fixed 1 yard = 0.9144 m exactly, so the inch, foot and mile are exact. ft: The international yard and pound agreement (1959) fixed 1 yard = 0.9144 m exactly, so the inch, foot and mile are exact.
Formula
ft = in ÷ 12
Derivation from SI units:
- 1 in = 2.54 cm = 0.0254 m (exact)
- 1 ft = 12 in = 0.3048 m (exact)
- 1 in = 0.0254 m ÷ 0.3048 m per ft = 0.08333333333333 ft
Both units are defined exactly, so the factor is exact. Inch definition: inch; Foot definition: foot.
