How many feet are in a centimetre?
One centimetre is 0.032808399 feet. To convert any amount, multiply by 0.032808399. Going the other way, one foot is 30.48 centimetres.
What is the formula to convert cm to ft?
Multiply the centimetre figure by 0.032808399. So ft = cm × 0.032808399. For a quick mental estimate, dividing by about 30.48 gets you close enough for most everyday purposes.
What does a centimetre actually look like?
One centimetre is about the width of an adult fingernail. The centimetre is the everyday metric unit for body measurements and paper sizes, though it is not an SI-preferred prefix step — engineers tend to jump from millimetres to metres.
And what is a foot?
One foot is about the length of a standard ruler. The foot is exactly 0.3048 metres. It survives in aviation worldwide — altitudes are given in feet almost everywhere, including in fully metric countries.
Is this conversion exact?
Yes. Since the 1959 international yard and pound agreement, the imperial and metric systems are related by exact definitions rather than measurements — the inch is exactly 25.4 mm and the pound exactly 0.45359237 kg. Everything derived from those, including this conversion, is therefore exact. Round at the end rather than partway through, since rounding cm before converting introduces an error the conversion then multiplies.

Getting it right
This conversion is exact by definition, so the only limit on accuracy is how many digits you keep. Round at the end rather than partway through — rounding cm to a whole number before converting introduces an error that the conversion then multiplies.
