Metres
—How to use this tool
Feet to metres, feet + inches to metres, or metres back to feet.
Fractions are fine; in feet + inches mode the inches must stay below 12.
Decimal feet, feet + inches, centimetres and total inches appear together.
Switch to metres → feet and the same length converts back — a built-in round-trip check.
Formula & worked example
10 ft × 0.3048 = 3.048 m exactly. 5 ft 10 in = (5 + 10 ÷ 12) × 0.3048 = 1.778 m. Back again, 1.778 m ÷ 0.3048 = 5.8333 ft = 5 ft 10 in.
Limitations — read this before you rely on it
The international foot (0.3048 m exactly) is used. The older US survey foot (0.3048006096 m) differs by about 2 parts per million and is not used here — it matters only for large land-survey distances.
