How do I convert centimetres to inches?

Converting from centimetres to inches isn't something you do often, however when the time comes that you need to, it can be confusing.

1 centimetre is roughly equivalent to 0.39 inches. Therefore, to convert from one to the other, you must multiply your length in centimetres by 0.39. This will give you the approximate measurement in inches.

For example, if you want to convert 40cm into inches the equation would be as follows:

40 x 0.39 = 15.6 inches
