CM to Feet
Divide centimetres by 30.48 and you have feet, because a foot is exactly 30.48 cm: 170 cm is 5.5774 ft and 180 cm is 5.9055 ft. The converter above opens with centimetres in the From box and feet in the To box, whatever you converted last, and it prints the answer as decimal feet to twelve significant digits. Feet and inches take one more step: keep the whole number of feet, then multiply what is left over by 12, so 5.5774 ft is 5 ft plus 0.5774 of a foot, which is 6.9 in. The list under the result already carries the same length in inches, millimetres, metres, yards and miles, and the chart at the foot of the page does the feet and inches split for the common heights between 150 cm and 200 cm.

Centimetres to feet, feet and inches, and inches
Every figure is the converter's own output for that number of centimetres, rounded for reading: feet to four decimals, inches to two, and the feet and inches column to the nearest tenth of an inch. The 30.48 cm and 152.4 cm rows are exact, which is why they read 1 and 5 with nothing after the decimal point.

Common questions
- How do I convert cm to feet?
- Divide by 30.48. A foot is exactly 30.48 cm, so 170 cm divided by 30.48 is 5.5774 ft and 100 cm divided by 30.48 is 3.2808 ft. Going the other way, multiply feet by 30.48: 5 ft is exactly 152.4 cm. The Swap units button between the two boxes turns this page into a feet to centimetres converter without reloading it.
- What is 170 cm in feet and inches?
- 5 ft 6.9 in. The converter prints 5.57742782152 ft as the headline, and the Inch row under it shows the same height as 66.9291338583 in. To read the headline as feet and inches, keep the 5 whole feet and multiply the 0.5774 that is left over by 12, which gives 6.9 in. The headline stays decimal feet because that is the number you paste into a spreadsheet; the chart below shows both forms together.
- Is a foot exactly 30.48 cm?
- Yes. The 1959 international agreement defines an inch as exactly 2.54 cm, and a foot is 12 inches, so a foot is exactly 30.48 cm and a metre is 3.28083989501 ft. The converter stores 0.3048 metres as the factor for a foot, so the arithmetic is exact and only the printed digits are rounded.
- How tall is 5 foot 7 in centimetres?
- 170.18 cm. Multiply the feet by 30.48 and the inches by 2.54, then add them: 5 times 30.48 is 152.4, and 7 times 2.54 is 17.78. On this page, choose Inch in the From box and type 67, since 5 ft 7 in is 67 inches, and the Centimetre row reads 170.18.
- Why does the result have so many decimal places?
- Because centimetres to feet rarely lands on a short decimal: 1 cm is 0.0328083989501 ft. Results are shown to 12 significant digits with trailing zeros dropped, so the exact cases stay clean, 152.4 cm comes out as 5 rather than 4.99999, and everything else keeps enough precision for you to round where you want. Results far above or below everyday sizes switch to exponential notation instead. Copy result copies the number exactly as printed, without the thousands separators.
- Does this send my measurements anywhere?
- No. There is no upload and no account. The conversion is arithmetic against a table of factors that ships with the page, so it runs in your browser and keeps working with no network connection once the page has loaded.
Conversion factors are the exact legal definitions where one exists. An inch is exactly 2.54 cm and a pound exactly 0.45359237 kg, so those conversions are exact rather than approximate. Temperature uses offsets rather than factors, and that is shown in the working.
