Symbol V. The space occupied by a body or mass of fluid.
Mathematics
A measure of the 3-dimensional space enclosed by a solid.
Chemistry
The space occupied by a body or mass of fluid.
Chemical Engineering
The three-dimensional space enclosed within or occupied by a body. For example, the volume occupied by a cylindrical vessel is equal to the cross-sectional area multiplied by the length. The volume occupied by a liquid can be determined from its mass divided by its density. The SI unit is m3.
Computer
A logical unit of data storage. A volume can be a single unit of a physical storage medium (e.g. one fixed disk may be a single volume), but it can correspond to part of a physical unit (e.g. one of several partitions on a fixed disk) or to more than one physical unit (e.g. multiple partitions on several fixed disks).
Electronics and Electrical Engineering
The magnitude of the complex audiofrequency signals in an audiofrequency transmission system.
Geography
On a GIS triangulated irregular network, three-dimensional space measured by length, width, and depth, or height.
