Feet to CM FAQ
Answers to the most frequently asked questions about converting feet and inches to centimetres.
To convert feet to centimetres, multiply the number of feet by 30.48 (since 1 foot equals 30.48 cm). If you also have inches, multiply the inches by 2.54 and add the two results together for the total centimetre measurement.
There are exactly 30.48 centimetres in one foot. This is a fixed conversion factor because both units are defined in terms of the metre: 1 foot = 12 inches, and 1 inch = 2.54 cm exactly.
Convert the feet to centimetres by multiplying by 30.48, then convert the remaining inches by multiplying by 2.54. Add both values together to get the total height or length in centimetres.
The conversion is mathematically exact, not approximate. Since 1959, the international foot has been defined as exactly 0.3048 metres, so multiplying by 30.48 always gives a precise centimetre value with no rounding error in the formula itself.
