Centimetre and Foot
Centimetres are the everyday metric length — body measurements, paper, furniture — and they are the one metric unit that has no direct customary counterpart, which is why so much converting happens through them.
A foot is twelve inches, and it is the unit heights and room sizes are quoted in across the United States. Aviation uses it worldwide for altitude, including in countries that use metres for everything else.

Convert cm to ft: common questions
How many feet are in a centimetre?
Exactly 0.0328083989501. One centimetre is 0.0328083989501 feet, and the box above will do it for any figure you type.
Is this conversion exact, or rounded?
The ratio is exact. It is not a rounded constant typed into a table: it is derived from the definitions of the two units, so it agrees with any other correct converter to as many digits as you care to compare.
Why does another converter show a slightly different number?
Almost always rounding rather than disagreement. Many converters cut the answer to two or four decimals, and some carry a factor that was rounded before the multiplication rather than after. The figures here are computed from the exact definitions and only rounded on the way to the screen.
Where these figures come from
The claims this page makes about length units are checkable, and these are the documents that settle them.
