Centimeter to Foot (cm to ft)
Result
0.03280839895 Foot
Formula
ft = cm × 0.03280839895
1 cm = 0.03280839895 ft, and 1 ft = 30.48 cm.
The metre is the SI base unit, defined by the speed of light. Since the 1959 international yard and pound agreement the imperial and US customary units are defined exactly in metres: 1 yard = 0.9144 m, so 1 foot = 0.3048 m, 1 inch = 2.54 cm and 1 mile = 1,609.344 m.
Worked examples
- 1 cm × 0.03280839895 = 0.032808399 ft
- 10 cm × 0.03280839895 = 0.32808399 ft
- 100 cm × 0.03280839895 = 3.2808399 ft
Common mistakes
- Decimal feet are not feet-and-inches: 5.75 ft is 5 ft 9 in, not 5 ft 7.5 in. Split off the whole feet and multiply the remainder by 12.
- A nautical mile (1,852 m) is about 15% longer than a statute mile (1,609.344 m). Knots and sea charts use nautical miles.
- The US survey foot (1200/3937 m) differs from the international foot by 2 parts per million. It was retired from official US use at the end of 2022 but still appears in older land records.
