volume (amount of physical bulk)

Part of the IT standards and organizations glossary:

Volume (symbolized V ) is a three-dimensional quantity representing amount or extent of physical bulk. The standard unit of volume in the International System ( SI ) is the meter cubed (m 3 ).

Volume is usually measured or defined in Euclidean (flat) three-space in Newtonian (non-relativistic) physics. We might speak of the volume of a particle, the volume of a sample of liquid or gas, or the volume of the earth. In relativistic physics, volume is determined for non-Euclidean (curved) three-space. In the case of certain complex or esoteric objects, volume might be impossible to define or measure. One example is a mathematical object having a fractional number of dimensions. Another example is an object without a well-defined surface.

When expressing large or small volumes, prefix multiplier s are attached to the meter cubed. The table below shows the most common alternative volume units and their relationship to the meter cubed.
