How to convert CM to INCHES
Centimeters and inches measure the same thing by different conventions. The US and a handful of other countries use inches; most of the world uses centimeters. You run into this conversion constantly: furniture dimensions listed in one system, product specs written in another, a clothing size chart that does not match what you are used to, or a recipe calling for a pan size you cannot picture.
The conversion factor is exact: one inch equals 2.54 centimeters, so divide your centimeter value by 2.54 to get inches. BoltConverter does that arithmetic instantly as you type, showing the result in decimal inches as well as the equivalent in feet and inches for measurements where both matter.
Type your centimeter value
Enter the number of centimeters in the input field. Decimals are fine, for example 30.5 cm.
