A '''physical quantity''' is a physical property of a phenomenon, body, or substance, that can be quantified by [[measurement]].

== Description ==

A physical quantity can be expressed as the combination of a magnitude expressed by a [[number]] – usually a [[real number]] – and a [[Unit (measurement)|unit of measurement]]; for example, 1.6749275×10−27 kg (the mass of the neutron), or 299792458 metres per second (the speed of light).

Physical quantities are measured as ''''nu'''' where '''n''' is the magnitude and '''u''' is the unit.

For example: A boy measured the length of a room as 3 m. Here 3 is the magnitude and m (metre) is the unit. 3 m can also be written as 300 cm. This shows that n1u1 =n2u2.

Almost all matters have quantity.
