How the Unit Converter works

One centimeter is 0.032808399 feet. Both units are defined against the same SI base unit, so the factor is derived from two exact definitions rather than measured. It is exact in principle and does not land on a round number.

Worked through: 170 cm x 0.032808399 = 5.57743 ft.

Going the other way, one foot is 30.48 centimeters.

To convert without a calculator, multiply by 0.03281. Rounding that to 0.033 is within 0.58% for most purposes.

Almost always a height question. Heights are read in feet and inches rather than decimal feet, so 180 cm is 5 ft 11 in rather than 5.91 feet; the calculator above gives both.

Precision is worth matching to the input. A measurement given as 100 cm carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
