Physical quantities are classified into two types. There are fundamental and derived quantities. Fundamental or base quantities are quantities which cannot be expressed in terms of any other physical quantities. These are length, mass, time, electric current, temperature, luminous intensity and amount of substance.

- A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as the combination of a numerical value and a unit. For example, the physical quantity mass can be quantified as n kg, where n is the numerical value and kg is the unit.
Scientists know many physical quantities, which are classified into basic and derived. ... The basic quantities are length, time, mass, charge, temperature, and the amount of substance. Although the basic quantities are undefined, the ratio of basic quantities of the same type is defined.
