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.

Millimeter (abbreviation: mm): is a unit of length in the SI metric system, equal to one thousandth of a metre. Therefore, there are thousand millimetres in a metre and ten millimetres in a centimetre.


How to Convert Centimeters to Millimeters

Example: How many millimeters are equivalent to 62.1 centimeters?


As;

1 centimeters = 10 millimeters

62.1 centimeters = Y millimeters

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

Y equals 62.1 times 10 over 1

(i.e.) Y = 62.1 * 10 / 1 = 621 millimeters

Answer is: 621 millimeters are equivalent to 62.1 centimeters.
