Convert 1 Centimeters to Millimeters (cm to mm) with our conversion calculator.

1 Centimeters to Millimeters equals 10 mm.

To convert 1 centimeter (cm) to millimeters (mm), we need to understand the relationship between the two units. In the metric system, a centimeter is larger than a millimeter. Specifically, 1 centimeter is equal to 10 millimeters. This conversion factor is fundamental to the metric system, where units progress in powers of ten. Therefore, to convert centimeters to millimeters, you multiply the number of centimeters by 10.

For our calculation:

1 cm × 10 = 10 mm

This calculation is straightforward because of the designed simplicity of the metric system. Starting with the base unit of a meter, which is the standard for measuring length in this system, each unit step (up or down) represents a tenfold change. A millimeter is one thousandth (1/1000) of a meter, and a centimeter is one hundredth (1/100) of a meter, so moving between millimeters and centimeters is a matter of multiplying or dividing by 10. This makes conversions within the metric system, such as from centimeters to millimeters, remarkably simple.
