CM to Feet
Divide centimetres by 30.48 and you have feet, because a foot is exactly 30.48 cm: 170 cm is about 5.5774 ft and 180 cm about 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 170 cm is 5 whole feet plus about 6.9 inches. Use the original length for this split to avoid rounding a rounded decimal again. 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.

Feet, yards and miles use international definitions. A light year uses a 365.25-day Julian year; the parsec coefficient is approximate.
Results round to 12 significant digits using the listed unit definitions. Input must have a finite numeric magnitude and at most 512 significant digits. Type a single decimal or scientific number; a matching From unit suffix is accepted. Commas and grouped spaces separate thousands; decimal commas, fractions and compound measurements are refused.

Centimetres to feet, feet and inches, and inches
This static chart converts each stated centimetre length using the exact international definitions and rounds 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. An international foot is exactly 30.48 cm, so 170 cm displays as 5.57742782152 ft (about 5.5774 ft) and 100 cm as 3.28083989501 ft (about 3.2808 ft). Going the other way, 5 ft is exactly 152.4 cm. Swap units reverses the pair without reloading. The exact factor does not make every decimal output exact; the display rounds to twelve significant digits.
- What is 170 cm in feet and inches?
- About 5 ft 6.9 in. The headline displays 5.57742782152 ft and the Inch row 66.9291338583 in. To split the original height manually, subtract 5 × 30.48 = 152.4 cm from 170 cm, then divide the remaining 17.6 cm by 2.54: 6.92913385827 in, or 6.9 in to one decimal place. The headline stays decimal feet, and the static chart below shows both forms. The converter does not accept or print a mixed feet-and-inches result in its main fields.
- Is a foot exactly 30.48 cm?
- Yes. The international inch is exactly 2.54 cm and a foot is 12 inches, so an international foot is exactly 30.48 cm. One metre displays as 3.28083989501 ft. The converter uses the exact decimal factor 0.3048 metres per foot, with rational arithmetic and a twelve-significant-digit rounded display. Historical US survey-foot values require a different definition.
- 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?
- Centimetres to feet rarely gives a short decimal: 1 cm displays as 0.0328083989501 ft. Decimal-rational arithmetic uses the defined factor and only the result display rounds, to twelve significant digits with trailing zeros dropped. Exact cases such as 152.4 cm = 5 ft stay clean. Magnitudes below one millionth or at least 10^15 use exponential notation. Copy result and each row copy the displayed numeric value without grouping commas; Copy complete conversion includes the input, units and conventions. Clipboard refusal leaves a selectable current summary.
- Does this send my measurements anywhere?
- Your measurements and converted values are calculated in the browser and are not uploaded by the converter. The definitions arrive with the page, so conversion needs no external data lookup and keeps working offline after the page has loaded. The core conversion needs no account.
Results round to 12 significant digits using the listed unit conventions. Many factors are exact definitions; psi and parsec use rounded coefficients. Temperature includes scale offsets. Days and weeks are fixed-duration units, and unit conversion does not determine calendar dates, ambient pressure or a software label’s convention.
