answered-by-expert Expert Answer

A physical quantity is expressed as a numerical value followed by a unit.

i.e., Physical quantity = Numerical value × Unit

For example: Force = 10 N

The numerical value denotes the magnitude of the quantity, whereas the unit denotes the type of quantity and the measurement system used.
