About Centimeters and Millimeters
One centimeter equals exactly 10 millimeters. Both are metric units, making this one of the simplest unit conversions — just multiply or divide by 10. Centimeters are used for everyday measurements like body dimensions, furniture, and clothing, while millimeters are used for precision work in engineering, jewelry, and medical imaging. A 2.5 cm tumor on a medical scan is 25 mm. A 3 cm drill bit is 30 mm. This conversion is especially important in technical drawings, where tolerances are expressed in millimeters but overall dimensions might be given in centimeters.
