How to use Centimeters to Inches
Type a value in centimeters and the inches figure appears straight away. The conversion table further down lists common values.
Heights in feet and inches
To turn a height in centimeters into feet and inches, divide by 2.54 to get inches, then divide by 12. 175 cm is 68.9 inches, which is 5 feet and 8.9 inches, so about 5 ft 9 in. Doctors, passports and most countries use centimeters, while people in the US usually give height in feet and inches.
Rough estimates without a calculator
One inch is a little over 2.5 cm, so dividing by 2.5 gets you close: 30 cm is about 12 inches, or one foot. For anything that has to fit, such as a frame, a TV mount or clothing, use the exact result above.
The formula
inches = cm ÷ 2.54
