Feet and inches to centimetres.
Convert ft + in to cm and cm to ft + in. Type in either box and the other follows. Type it the way you say it — "5 ft 9 in", "5' 9" or just "5 9" — and the centimetres follow.
| ft + in | cm |
|---|---|
| 4 ft 6 in | 137.16 cm |
| 5 ft 0 in | 152.4 cm |
| 5 ft 3 in | 160.02 cm |
| 5 ft 6 in | 167.64 cm |
| 5 ft 9 in | 175.26 cm |
| 6 ft 0 in | 182.88 cm |
| 6 ft 3 in | 190.5 cm |
| 6 ft 6 in | 198.12 cm |
- The whole feet are kept whole and only the remainder becomes inches, which is why the answer reads the way people say it.
Definitions
- Feet and inches together, the way height is actually said. Twelve inches to the foot, and the inch is exactly 25.4 mm.
- The centimetre is a hundredth of a metre. It is the everyday metric unit for body and furniture measurements outside engineering.
- This conversion is exact by definition. 1 ft 0 in = 30.48 cm.
- The metre is SI; every imperial and US customary length here is defined exactly in terms of it by the 1959 international yard and pound agreement.
How it works
One direction multiplies and the other divides by the same number, so nothing is lost by going back and forth.
The value passes through m, the unit every other length & distance unit on the site is defined against, rather than a number written into this page on its own. That is why the figure here, the figure in the table above and the general length & distance converter always agree.
Display precision limits significant figures rather than decimal places, because one fixed number of decimals is useless across a range this wide. Very large and very small results switch to scientific notation with a proper superscript exponent. The editable box always holds a plain number at full working precision, so you can carry on from either side.
Common questions this answers: what 5 ft 9 in is in centimetres (175.26 cm), how many inches make a foot (12), and how to type it — "5 ft 9 in", "5' 9"" or just "5 9" are all accepted.
