VOL

Vol is commonly used as an abbreviation for volume. It appears in a variety of contexts, including measurements of space, bibliographic references, and everyday references to loudness or capacity. The term is frequently seen in catalogs, scientific writing, and technical manuals.

In mathematics and physics, volume denotes a three‑dimensional measure of the amount of space enclosed by a closed boundary. It is a geometric property with units such as cubic meters or liters. The symbol vol may be used in formulas to indicate the volume of a region or object, and discussions of volume often involve methods from calculus or measure theory.

In publishing and libraries, vol. or Vol. is a standard abbreviation for a volume of a multivolume work or for a single issue of a periodical. Citations routinely include vol. and often issue numbers to identify the specific part of a larger run. This usage helps organize and reference serial publications and book series.

In finance and economics, vol stands for volatility, a statistical measure of the degree to which a security’s price fluctuates over time. It is a key input in risk assessment, portfolio management, and derivatives pricing, typically expressed as an annualized standard deviation or a related metric.

In computing and electronics, vol also denotes volume, the control that adjusts loudness on audio devices. The term appears on equipment controls and displays, and in the DOS/Windows command line, VOL is a command that displays the disk’s volume label and serial number.

Overall, vol functions as a compact shorthand across disciplines for the concept of volume, whether referring to physical space, a published part, or a measure of variation.
