What this converter does
This converter turns feet into metres and back instantly. It also handles inches, millimetres, kilometres, miles and yards — every pair uses an exact, internationally fixed factor. Type a value, pick your units, and read the answer as you type.
One foot is exactly 0.3048 metres, so 10 feet is 3.048 metres. The metre is the SI base unit of length, fixed by the speed of light per NIST.
The units it covers
Every length unit converts through the metre, the SI base unit, with a fixed ratio.

The formula
Each unit has a fixed value in metres, so converting means going through the metre once:
result = value × factor_from ÷ factor_toWhere:
- value = the number you typed
- factor_from = the “from” unit’s value in metres
- factor_to = the “to” unit’s value in metres
Worked example
Convert 10 feet to metres.
1 ft = 0.3048 m10 × 0.3048 = 3.048 mSo 10 feet is 3.048 metres.
The units in this example
An imperial and US customary unit equal to exactly 0.3048 m, still standard for construction in the US and UK.
- 1 ft = 0.3048 m
- 1 ft = 12 in
- 1 ft = 30.48 cm
- 3 ft = 1 yd
The SI base unit of length, used across most of the world for everything from building dimensions to distances.
- 1 m = 3.281 ft
- 1 m = 39.37 in
- 1 m = 100 cm
- 1 m = 1.094 yd
