Feet to Centimeters Converter
Convert ft to cm instantly — height, rooms, and DIY.
Type a length in feet and get the exact centimeter equivalent instantly. The converter multiplies by the exact 30.48 cm per foot — the international definition, not an approximation.
How it's calculated
centimeters = feet × 30.48. The factor is exact: the international foot is defined as 0.3048 meters.
How the foot-to-centimeter conversion works
Since 1959 the international foot has been defined as exactly 0.3048 meters, which is exactly 30.48 centimeters. Converting feet to centimeters is therefore one multiplication: centimeters = feet × 30.48. Every result is exact by definition.
Heights written as feet and inches need one extra step first: convert the inches to a decimal. Five foot nine is 5 + 9 ÷ 12 = 5.75 ft, and 5.75 × 30.48 = 175.26 cm. The input box accepts decimals, so you can type 5.75 directly.
Common foot to centimeter reference points
Whole-foot anchors: 1 ft is 30.48 cm, 3 ft (a yard) is 91.44 cm, 5 ft is 152.4 cm, 6 ft is 182.88 cm, and 10 ft is 304.8 cm. Room dimensions like 12 ft × 15 ft become 365.76 cm × 457.2 cm — the numbers European flooring and furniture sites expect.
Height landmarks: 5 ft 6 in is 167.64 cm, 5 ft 9 in is 175.26 cm, 6 ft 0 in is 182.88 cm, and 6 ft 2 in is 187.96 cm. Memorize 1 ft ≈ 30.5 cm and 1 in ≈ 2.54 cm and you can sanity-check any result in seconds.
Where you'll use feet to centimeters
Buying furniture, rugs, or curtains from international sellers is the classic case — US listings give feet while metric shops need centimeters. A 8 ft rug is 243.84 cm; knowing that before ordering avoids an expensive return.
Travel forms, visa applications, and medical paperwork in metric countries ask for height in centimeters, and DIY projects mixing US plans with metric materials need every cut converted. One exact factor handles all of it.
