Exact method
How height conversion works
One international inch equals exactly 2.54 centimeters, and one foot equals exactly 12 inches. The calculator first turns a mixed height into total inches, then multiplies by 2.54.
centimeters = (feet × 12 + inches) × 2.54
To convert the other way, divide centimeters by 2.54, divide the total inches into groups of 12, and keep the remainder as inches.
Worked example
What is 5 feet 9 inches in centimeters?
- Multiply 5 feet by 12 to get 60 inches.
- Add 9 inches for a total of 69 inches.
- Multiply 69 by 2.54 to get 175.26 centimeters.
Therefore, 5′ 9″ = 175.26 cm = 1.7526 m.
