A millimeter is one thousandth of a meter.
Millimeters are widely used where fine physical detail and small tolerances matter.
Mathematically, millimeter (mm) = centimeter (cm) multiplied by the conversion factor shown below.
1 cm = 10 mm
1 mm = 0.1 cm
1 cm x 10 = 10 mm
The distance in millimeter (mm) is the distance in centimeter (cm) multiplied by 10.
