Understanding feet and centimeters
What are feet (ft)?
A foot (ft) contains 12 inches. Decimal feet describe fractions of a foot: 5.5 ft means 5 feet 6 inches.
What are centimeters (cm)?
A centimeter (cm) is one hundredth of a meter. One inch equals exactly 2.54 cm, so 12 inches equal 30.48 cm.
How to use this converter
- Enter decimal feet.
- For feet and inches, divide the inches by 12 and add them to the feet first.
- Read the answer in centimeters. For 5 feet 6 inches, enter 5.5.
The conversion formula
centimeters = feet × 30.48
A worked example
For 5 feet 6 inches, calculate 5 + 6 ÷ 12 = 5.5 ft. Then 5.5 × 30.48 = 167.64 cm.
For 5 feet 8 inches, you can avoid rounding decimal feet by calculating each part: 5 × 30.48 + 8 × 2.54 = 172.72 cm. Entering 5.8 feet would instead give 176.784 cm.
