What is volume?Volume is a measure of the amount of three-dimensional space occupied by an object. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.
InputCubic Centimeter is the volume of a cube with edge length of one centimeter (1/100 of a meter), which is exactly equal to one milliliter.
Imperial Gallon is defined as exactly 4.54609 litres (277.4194 cubic inches). It is used in some Commonwealth countries.
