Method and sources
This converter uses pure arithmetic and no external dataset. The only constant is the international definition of the inch as exactly 2.54cm, agreed in the International Yard and Pound Agreement of 1959.
Feet-and-inches results are rounded to the nearest half inch, matching how heights are usually written. Centimetre results are shown to one decimal place.
For a quick look-up, the cm to feet and inches chart lists every height from 140 to 210 cm.
Frequently asked questions
How do I convert cm to feet and inches?
Divide the height in centimetres by 2.54 to get total inches, then divide by 12 for whole feet, keeping the remainder as inches. For example, 170cm ÷ 2.54 = 66.9 inches, which is 5 feet 6.9 inches — rounded to the nearest half inch, 5'7".
How many inches is 1cm?
1cm is exactly 0.3937 inches (1 ÷ 2.54). This conversion factor — 2.54cm per inch — has been the international standard since 1959 and is exact, not an approximation.
What's the difference between feet-inches and total inches?
Feet-inches (e.g. 5'7") splits a height into whole feet plus the remaining inches. Total inches (e.g. 67 inches) expresses the same height as one number. Both describe the same height; total inches is more useful for maths, feet-inches is the more familiar everyday format in the US and UK.
Why does my height in feet and inches sometimes round differently?
This converter rounds to the nearest half inch (0.5"), which matches how heights are usually written and measured in practice. A height ending in exactly .25in rounds to the nearest .5in, so you may occasionally see a small (under 1cm) difference versus a converter that keeps more decimal places.
Is 1 metre the same as 100cm?
Yes — a metre is defined as exactly 100 centimetres, so converting is just moving the decimal point: 1.70m is the same height as 170cm.
