How do you convert cm to feet and inches?
Divide the height in centimetres by 2.54 to get total inches. The whole feet are the total inches divided by 12 (rounded down), and the remaining inches are what is left over. To reverse it, multiply feet × 12 plus inches by 2.54 to get centimetres, since one inch equals exactly 2.54 cm.
Formula
How this is calculated
Height conversion rests on a single exact definition: since 1959 the international inch equals exactly 2.54 centimetres, and one foot is exactly 12 inches. No measured constants or approximations enter the maths, so the only error is from how the result is displayed.
Going from centimetres to feet and inches, the centimetre value is divided by 2.54 to get the total number of inches. The whole feet are that total divided by 12 and rounded down (the floor), and the inches are the remainder, rounded to the nearest whole inch for a clean reading. A guard handles the edge case where rounding pushes the inches to 12 (for example 11.6 in): it carries one foot up and resets inches to 0 so you never see "5 ft 12 in". Going the other way, feet are multiplied by 12 and the inches added, then the total inches are multiplied by 2.54 to give centimetres.
Metres are simply centimetres divided by 100, and total inches are centimetres divided by 2.54. A blank feet or inches field is treated as zero so you can enter just one. Centimetre and metre figures are exact; only the displayed feet-and-inches reading is rounded.
Examples
| Input | Result |
|---|---|
| 175 cm → ft/in | 5 ft 9 in (1.75 m) |
| 180 cm → ft/in | 5 ft 11 in (1.8 m) |
| 6 ft 0 in → cm | 182.88 cm (1.829 m) |
About this calculator
Height is recorded in centimetres in most of the world but in feet and inches in the US and UK, so converting between the two is a common task for passports, fitness apps, medical forms and online profiles. This converter works in both directions and is based on the international inch, which is defined as exactly 2.54 centimetres.
To go from centimetres to feet and inches, divide the centimetres by 2.54 to get the total inches, take the whole feet as the total inches divided by 12 (rounded down), and the remaining inches as the leftover. To go the other way, multiply the total inches (feet × 12 + inches) by 2.54 to get centimetres. One metre is 100 centimetres, so the height in metres is simply the centimetre value divided by 100.
Frequently asked questions
175 cm is about 5 feet 9 inches (5 ft 8.9 in exactly), or 1.75 metres.
6 feet equals 72 inches, and 72 × 2.54 = 182.88 cm, which is about 1.83 metres.
Yes. Since 1959 the international inch has been defined as exactly 2.54 centimetres, so all cm ↔ ft/in conversions here are exact before rounding.
