Feet and inches to centimetres
One inch is exactly 2.54 cm and a foot is 12 inches, so multiply the feet by 12, add the inches, and multiply by 2.54. Type in either box and the other updates as you go.
| ft in | cm | ft in | cm |
|---|---|---|---|
| 5 ft 0 in | 152.4 | 5 ft 8 in | 172.7 |
| 5 ft 2 in | 157.5 | 5 ft 10 in | 177.8 |
| 5 ft 4 in | 162.6 | 6 ft 0 in | 182.9 |
| 5 ft 6 in | 167.6 | 6 ft 2 in | 188.0 |
Common questions
Why 2.54 exactly, not a rounded number?
That's the exact international definition of an inch (fixed by treaty in 1959), so the conversion is exact — no rounding error, unlike some older imperial-metric conversions that used approximations.
What if I only know my height in feet, no inches?
Enter 0 for inches — the conversion still works fine with just the whole-foot number.
