Feet to Centimeters Converter
Change feet into centimetres with a single multiplication. A foot is exactly 30.48 centimetres, a value that drops out of the 1959 definition of the inch as 2.54 cm with twelve inches per foot, so every result is exact. Enter a length in feet and the tool shows the centimetre equivalent, plus a quick table of common values. It is the conversion you want when recording a height from feet into a metric medical record, fitting a US-spec sofa into a room measured in centimetres, marking out a garden bed planned in feet, or reading an American floor plan against a metric tape.

- Multiply it by 30.48, since one foot equals exactly 30.48 centimetres.
- The answer is that distance in centimetres.
- To go back, divide a centimetre figure by 30.48 to recover feet.
- For mental arithmetic, multiply by 30: 5 feet is roughly 150 cm, with the true value a shade higher at 152.4 cm.
centimetres = feet × 30.48
A foot measures exactly 30.48 centimetres, so multiplying a length in feet by that constant returns the same length in centimetres. Dividing centimetres by 30.48 reverses it. The factor is fixed, making this one steady multiplication.
