Physical quantity


A physical quantity is either a quantity within Physics that can be measured (e.g. mass, volume, etc.), or it is the result of measurement and usually expressed as the product of a numerical value and a physical unit (whereby SI units are usually preferred).

Example

: P = 42.3 x 103 W = 42.3 kW where P represents the physical quantity of power 42.3 x 103 is the numerical value k is the SI prefix kilo representing 103 W is the symbol for the unit of power, the watt kW is the kilowatt (= 103W)

Subscripted variables

Usually, the symbols for physical quantities are chosen to be a single letter of the Latin or Greek alphabet, printed in italic. Both lower and capital letters are used. Often, the symbols are modified by subscripts or superscripts. If these sub- or superscripts are themselves symbols for physical quantities or numbers, they are printed in italic. Other sub- and superscripts are printed upright (roman).
