Convert Centimeters to Inches

50 centimeters is 19.69 in. One centimeter is exactly 0.393700787402 inches.

50 centimeters is 19.685039 inches, because one centimeter is 0.39370079 inches. To convert centimeters to inches, multiply by 0.39370079; to go the other way, divide by 0.39370079 or multiply by 2.54. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST. One hundredth of a meter, and the unit most of the world states height in.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.

The same converter answers this pair however it is written: centimetres to inches is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
