A centimeter (cm), also spelled centimetre, is a metric unit of length in the International System of Units. The centi- prefix means one hundredth.
One centimeter is equal to 1/100 of a meter (m), 10 millimeters (mm), and 1/2.54 of an inch.
Mathematically, centimeter (cm) = millimeter (mm) multiplied by the conversion factor shown below.

1 cm = 10 mm
1 mm x 0.1 = 0.1 cm
The distance in centimeter (cm) is the distance in millimeter (mm) multiplied by 0.1.
distance(cm) = distance(mm) x 0.1
Or:
cm = mm x 0.1
Formula: value × 0.1
Example: 15 mm = 1.5 cm
