In liquid measurements, a cc, always in lower case, means cubic centimeter. A cubic centimeter can be used as a measurement for the volume of anything, not just liquids. This unit is part of the modern form of the metric system and is equal to a milliliter.

A cubic centimeter can also be written as cm³. A single cubic centimeter is equivalent to 0.03 U.S. fluid ounce, as 1 U.S. fluid ounce is equal to 25.97 cubic centimeters. A single U.S. pint is equal to 473.18 cubic centimeters. There are 1,000 cubic centimeters in 1 liter and 1 million cubic centimeters in 1 cubic meter, which is usually expressed as 1 m³.
