How it’s calculated
A foot is exactly 12 inches in both the US and the UK; the international foot (0.3048 m) has been the same everywhere since 1959.
1 ft = 12 in (exact) · 1 in ≈ 0.083333333 ft
in = ft × 12
- Multiply the value in feet by 12.
- To go back, divide by 12 (or multiply by 0.08333333333).
- 1 ft = 12 in · 1 in = 0.08333333333 ft
