Millimeters to Centimeters

A millimeter (symbol: mm) is a unit of length in the International System of Units (SI). One millimeter is equal to one-thousandth (1/1,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for 10^-3. Millimeters can be abbreviated as mm; for example, 1 millimeter can be written as 1 mm.

A centimeter (symbol: cm) is a unit of length in the International System of Units (SI), the current form of the metric system. It is defined as 1/100 meters. The centimeter, like the meter, is used in all sorts of applications worldwide (in countries that have undergone metrication) in instances where a smaller denomination of the meter is required. Height is commonly measured in centimeters outside of countries like the United States.

How to convert millimeters to centimetes

1 mm is equal to 0.1 centimeters:

1 mm = 0.1 cm

The distance d in centimeters (cm) is equal to the distance d in millimeters (mm) divided by 10:

d_(cm) = d_(mm) / 10

Example

Convert 20 millimeters to centimeters:

d_(cm) = 20mm / 10 = 2cm
