How to Convert Millimeters to Cubic Centimeters

Two units of distance in the metric system are centimeters and millimeters. To find the volume of an object, the metric system uses cubic centimeters, or cm^3, and cubic millimeters, or mm^3. To accurately convert between cubic millimeters and cubic centimeters, you need to know the conversion factors. Each cubic millimeter equals 0.001 cubic cm.

Calculator

Instructions

- 1
  Divide the number of cubic millimeters by 1,000 to convert to cubic centimeters. For example, if you have a volume of 725 cubic mm, divide 725 by 1,000 to get 0.725 cubic cm.
- 2
  Multiply the number of cubic millimeters by 0.001 to verify your conversion to cubic centimeters. In this example, multiply 725 by 0.001 to get 0.725 cubic cm.
- 3
  Confirm your conversion with an online cubic-millimeters-to-cubic-centimeters converter (see Resources). Enter the number of cubic millimeters and press "Go."
