Converting height both ways

This height calculator converts between the two systems most people use for height: feet and inches, and centimetres. As a height converter it takes a height in either and shows the other, plus metres and total inches, so you can read your height in cm at a glance. It works both directions, so it doubles as a cm to feet and a feet to cm converter, which is handy when a form or a friend abroad uses the system you do not.

How the conversion works

The conversion rests on one exact fact: one inch is exactly 2.54 centimetres. From there, a height in feet and inches becomes total inches (feet times 12, plus the inches), then multiplies by 2.54 to give centimetres. Going the other way, centimetres divide by 2.54 for total inches, and that splits back into feet and inches. Because the inch is defined exactly, the conversion is precise, not an approximation.

A worked example

A height of 5 feet 9 inches is 69 inches in total. Multiply by 2.54 and you get 175.26 centimetres, or about 1.75 metres. Going back, 180 centimetres is 70.87 inches, which is 5 feet 10.9 inches.

FAQ

How do I convert feet and inches to cm?

Turn the height into total inches (feet times 12 plus inches), then multiply by 2.54. For 5 feet 9 inches that is 69 times 2.54, or about 175.3 cm. The tool does it instantly.

How do I convert cm to feet and inches?

Divide the centimetres by 2.54 to get total inches, then split that into feet and inches. For 175 cm that is about 5 feet 8.9 inches.

How many cm are in an inch?

Exactly 2.54. That fixed definition is what makes height conversions precise rather than rounded estimates.

What is my height in metres?

Divide your height in centimetres by 100. So 175 cm is 1.75 metres. The tool shows metres alongside the other units.
