Choose the conversion direction and enter feet and inches or centimeters. Total inches equal 12 times feet plus the remaining inches. The exact NIST conversion is 2.54 centimeters per inch; reverse conversion divides by that factor.

Height Converter: formula
Common error: Treating the inches as a decimal part of a foot. Five feet nine is 5.75 feet, not 5.9, because there are twelve inches in a foot.
An exact unit factor does not improve the precision of the original measurement. Round only after converting. The input does not accept mixed meters-and-centimeters notation; enter its total centimeters.
This converts units rather than choosing a clinical height-measurement protocol.

Height is quoted in feet and inches in one place and in centimeters in another, and the conversion has an awkward twelve in it. Five feet nine inches is 69 inches, which is 175.26 centimeters at 2.54 centimeters an inch. Going the other way, 175 centimeters is 68.9 inches, or 5 feet 8.9 inches.
Reference values: 6 feet is 182.88 centimeters, and 170 centimeters is about 5 feet 7 inches. A meter is about 39.37 inches, and an inch is exactly 2.54 centimeters.
Choose the direction first. The feet and inches fields drive the answer when you convert one way, and the centimeter field drives it the other way.
See the BMI and healthy weight range calculators, which use height, and the length converter for other lengths. The body surface area and ideal weight pages also use height. The weight converter changes weights between pounds and kilograms.
How many centimeters is 5 feet 9 inches?
About 175.3 centimeters, calculated as 69 inches times 2.54.
How do I convert centimeters to feet and inches?
Divide by 2.54 to get inches, then divide by 12 for feet and keep the remainder as inches.
When should I measure height?
In the morning, standing against a wall without shoes, since height decreases slightly through the day.
