Height Converter
Convert any height between centimeters and feet/inches instantly, in both directions.
Example
A height of 170 cm converts to 5' 6.9" (about 66.9 total inches, or 1.70 m). Going the other way, 5 ft 7 in equals 170.2 cm.
How it works
1 inch = 2.54 cm, so cm = (feet x 12 + inches) x 2.54, and to go the other way total inches = cm / 2.54, with feet = floor(inches / 12) and remaining inches = inches mod 12.
Good to know
The Height Converter turns a height written in centimeters into feet and inches, or the reverse, the moment you type. It's the everyday tool for anyone caught between metric and imperial systems: filling out a US visa or job application that wants feet/inches, reading a European passport or medical chart in centimeters, comparing your own height against an athlete's stats, or quoting a doorway, mirror, or growth-chart measurement to someone in another country.
Pick a direction with the toggle at the top, then type into the field. The big number is your converted height, and the four stat tiles break the same value into centimeters, feet and inches, total inches, and meters so you can copy whichever format the form in front of you is asking for. Total inches is handy for spreadsheets and BMI formulas; meters is the one to grab for height-squared health calculations.
One thing worth knowing: the inches reading carries a decimal (for example 5' 6.9") because most centimeter heights don't fall exactly on a whole inch. That decimal is the accurate answer, not an error. If a form only accepts whole inches, round it yourself, but be aware that rounding 6.9" up to 7" nudges your stated height by roughly a centimeter.
- cm to ft/in: enter a single centimeter value, ideal for converting a clinic or tape-measure reading.
- ft/in to cm: enter feet and inches separately, ideal for converting a height you already know in imperial.
Frequently asked questions
How many centimeters are in a foot?
There are 30.48 cm in one foot, since a foot is 12 inches and each inch is exactly 2.54 cm (12 x 2.54 = 30.48).
Why does the inches value have a decimal?
Centimeters rarely land on a whole inch, so the converter shows the leftover as a decimal (e.g. 5' 6.9") for accuracy. You can round to the nearest inch if you only need an approximate height.

Should I round my height up or down on a form?
Round to the nearest whole inch rather than always up or down, so the stated height stays closest to your real measurement. For official documents, follow whatever rounding rule the form specifies, or enter the decimal if it allows one.
How many inches is 5 feet 9 inches in total?
5 feet 9 inches is 69 total inches, since 5 feet is 60 inches plus the extra 9. In centimeters that is about 175.3 cm.
Is a foot exactly 30 cm?
No, a foot is 30.48 cm exactly, not a round 30. The 0.48 cm difference adds up over taller heights, so use the precise value for anything that matters.
Does this height converter work without internet?
