How it’s calculated
1 ft = 12 in · 1 in = 2.54 cm exactly · 1 ft = 30.48 cm
cm = (feet × 12 + inches) × 2.54
Step by step
- Turn the feet into inches: 5 × 12 = 60 in.
- Add the inches: 60 + 7 = 67 in.
- Multiply by 2.54 (cm per inch, exact): 67 × 2.54 = 170.18 cm.

FAQ
Heights on passports, medical forms and sports rosters outside the US are usually in centimetres; this converter gives the figure to one decimal place and to 5 significant figures.
How do I convert feet and inches to centimetres?
Turn the height into inches first (feet × 12 + inches), then multiply by 2.54. For 5 ft 7 in: 5 × 12 + 7 = 67 in, and 67 × 2.54 = 170.18 cm.
How do I convert centimetres to feet and inches?
Divide the centimetres by 2.54 to get inches, then divide by 12. The whole number is the feet and the remainder is the inches. 180 cm ÷ 2.54 = 70.87 in = 5 ft 10.87 in, which most people round to 5 ft 11 in.
Is a foot the same in the US and the UK?
Yes. Since 1959 both countries use the international foot of exactly 0.3048 m (12 inches of 2.54 cm), so a height in feet and inches means the same thing on either side of the Atlantic.
How tall is 5 foot 9 in cm?
5 ft 9 in is 69 inches, and 69 × 2.54 = 175.26 cm.
Why does Unitglide show inches with decimals?
