The working
How many feet and inches is 175 cm?
Divide centimetres by 2.54 to get inches, then divide by 12 for feet. 175 cm is 68.9 inches, which is 5 feet 8.9 inches. To go the other way, multiply total inches by 2.54. One foot is exactly 30.48 centimetres.
Centimetres and inches in daily life
Centimetres are used for height in health records, school forms and clothing sizes, while many English-speaking countries use feet and inches. If you are applying for an overseas visa, filling in a dating profile or buying clothes online from the US or UK, you will see both. The conversion is the same each time, which makes it easy to check.
Measuring height properly
Stand with your back against a wall, heels together and head level, and mark the top of your head with a flat book. Measure in the morning, because people are slightly taller after lying down, by as much as a centimetre or two. Enter the figure to the nearest half centimetre.
To check a healthy weight for your height, use the BMI calculator.
How this is calculated
The rule, step by step, so you can check any figure by hand.
1 inch = 2.54 centimetres (exact)1 foot = 12 inches = 30.48 centimetresinches = centimetres รท 2.54feet = whole 12s in the inches; the rest are inchesmetres = centimetres รท 100
The inch is defined as exactly 2.54 centimetres, so a conversion is exact apart from the rounding you choose to show. A person's height in centimetres is typically measured to the nearest half centimetre, while in feet and inches it is quoted to the nearest inch, so converting both ways can shift the result by a centimetre or so.
Height measured by a doctor or a health service is recorded in centimetres here. If you are filling in an overseas form, you may need feet and inches, and the calculator gives the exact figure to round as the form requires.
