The Challenge
Feet to centimeters conversions come up whenever US measurements need to meet metric standards. A 6-foot person filling out a European medical form needs 182.88cm. A US home with 9-foot ceilings needs that in centimeters for a European contractor: 274.32cm. Lumber cut to 8 feet is 243.84cm. A 5-foot-10 athlete listed on a US roster is 177.8cm on a European team sheet. The exact conversion: multiply feet by 30.48 to get centimeters. For feet and inches together, convert inches to centimeters separately (multiply by 2.54) and add. Reference points: 1 foot = 30.48cm exactly, 5 feet = 152.4cm, 6 feet = 182.88cm, 10 feet = 304.8cm.

Why 30.48 Is the Exact Conversion Factor
1 foot = 30.48 centimeters is not an approximation — it is a mathematical consequence of a defined international standard. The 1959 International Yard and Pound Agreement defined 1 yard as exactly 0.9144 meters. Divide by 3 to get 1 foot = 0.3048 meters = 30.48 centimeters exactly. No rounding occurs anywhere in the chain. This replaced the older US survey foot (0.3048006 meters), which was used for geodetic land measurement and differed by about 3 parts per million — enough to matter across state-level survey distances, irrelevant for everyday construction.
Converting a Mixed Feet-and-Inches Value to Centimeters
- Write out the full measurement — example: 5 feet 11 inches
- Multiply feet by 30.48: 5 × 30.48 = 152.4cm
- Multiply inches by 2.54: 11 × 2.54 = 27.94cm
- Add both results: 152.4 + 27.94 = 180.34cm — that is 5 feet 11 inches exactly

Frequently Asked Questions
How many centimeters is 1 foot?
1 foot equals exactly 30.48 centimeters. This is a defined value — the 1959 International Yard and Pound Agreement set 1 yard as exactly 0.9144 meters, making 1 foot = 0.3048 meters = 30.48 centimeters with no rounding or approximation.
How do I convert feet and inches to centimeters?
Multiply feet by 30.48, multiply inches by 2.54, then add the two results. Example: 5 feet 9 inches. 5 × 30.48 = 152.4cm. 9 × 2.54 = 22.86cm. 152.4 + 22.86 = 175.26cm. Shortcut: convert everything to inches first (5 × 12 + 9 = 69 inches), then multiply by 2.54. 69 × 2.54 = 175.26cm — same result.
What is 5 feet in centimeters?
5 feet = 5 × 30.48 = 152.4cm exactly. This is a clean result because both 5 and 30.48 produce no rounding. 152.4cm is also 1524mm and 1.524 meters.
What is 6 feet in centimeters?
6 feet = 6 × 30.48 = 182.88cm. This is the exact value — 180cm, which is sometimes casually called '6 feet,' is actually 5 feet 10.87 inches. True 6 feet is 182.88cm, a difference of 2.88cm. On medical or official documents, use 182.88cm if the measurement is 6 feet.
What is 5 feet 10 inches in centimeters?
5 feet 10 inches = 70 inches total. 70 × 2.54 = 177.8cm. Or: (5 × 30.48) + (10 × 2.54) = 152.4 + 25.4 = 177.8cm. This is the commonly cited average male height in the United States.
How do ceiling and room heights in feet convert to centimeters?
Common ceiling heights: 7ft=213.36cm, 8ft=243.84cm, 9ft=274.32cm, 10ft=304.8cm, 12ft=365.76cm. Room dimensions: 10×12ft=304.8×365.76cm, 12×15ft=365.76×457.2cm, 15×20ft=457.2×609.6cm. US standard new construction ceiling is 8 feet (243.84cm); European apartments typically run 250–270cm.
What is 5 feet 7 inches in centimeters?
5 feet 7 inches = 67 inches total. 67 × 2.54 = 170.18cm. This is close to 170cm — the difference is 0.18cm, negligible for most purposes. For forms requiring exact centimeters, use 170.18cm.
