Volume units conversion for metric, US customary (both liquid and dry) and imperial measurement systems including several commonly used historical units.

In metric system (SI), the base volume unit is cubic metre ("meter" is American spelling). Every length unit has a corresponding volume unit and the volume of a cube is calculated by multiplying the length of a side by itself twice.

The most frequently used volume units are liter (1 cubic decimeter), milliliter (1 cubic centimeter), fluid ounce, cup, pint, quart, gallon, cubic meter, cubic feet and cubic yard.

Although many volume units are the same in imperial and US customary system (cubic inch, cubic feet etc), several US customary units are grouped into two categories to measure liquid and dry volume capacities separately.
