To convert centimeters into millimeters you need to know how that much one centimeter equals 10 millimeters. So you times the number of centimeters by ten to convert to millimeters. Here's an example: Convert 12 centimeters to millimeters. 12 cm x 10 mm/cm = 120 mm Note that our conversion factor is 10 millimeters per 1 centimeter, or 10 mm/cm. The cm units will "cancel out" and leave the answer in millimeters.
1 inch = 2.54 centimeters
You cannot convert a unit of length (Centimeter) to a unit of volume (Cubic Centimeters).
