Centimeter (abbreviation: cm): is a unit of length in the SI metric system, equal to one hundredth of a metre, centi being the prefix for a factor of 1/100. The centimetre was the base unit of length in the now deprecated centimetre–gram–second (CGS) system of units.

Inch (abbreviation: in): is a unit of length in the (British) imperial and United States customary systems of measurement now formally equal to 1/36 yard but usually taken as 1/12 of a foot.

How to Convert Centimeters to Inches

Example: How many inches are equivalent to 28.97 centimeters?


1 centimeters = 0.393701 inches

28.97 centimeters = Y inches

Assuming Y is the answer, and by criss-cross principle;

Y equals 28.97 times 0.393701 over 1

(i.e.) Y = 28.97 * 0.393701 / 1 = 11.40551797 inches

Answer is: 11.40551797 inches are equivalent to 28.97 centimeters.
