A physical quantity is a physical property of a phenomenon, body, or substance, that can be quantified by measurement.^{[1]} A physical quantity can be expressed as the combination of a magnitude expressed by a number – usually a real number – and a unit; 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 n u {\textstyle nu} where n {\textstyle n} is the magnitude and u {\textstyle 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. The same physical quantity x {\textstyle x} can be represented equivalently in many unit systems, i.e. x = n 1 u 1 = n 2 u 2 {\textstyle x=n_{1}u_{1}=n_{2}u_{2}} .
