The physical quantities obtained from the combinations of base quantities are known as derived quantities, and the units used to define these quantities are known as derived units. For example, the speed of a moving car from one point to another is defined as the distance traveled divided by travel time.
Each of these physical quantities is then known as a derived quantity and each unit is called a derived unit. The choice of base quantities is somewhat arbitrary, as long as they are independent of each other and all other quantities can be derived from them.

Derived quantities are those physical quantities which are derived from the basic or fundamental quantities by multiplication or division. They cannot be measured directly but can be calculated using the fundamental quantities.
Each of these physical quantities is then known as a derived quantity and each unit is called a derived unit. The choice of base quantities is somewhat arbitrary, as long as they are independent of each other and all other quantities can be derived from them.
All other physical quantities, such as force and electric charge, can be expressed as algebraic combinations of length, mass, time, and current (for example, speed is length divided by time); these units are called derived units.
Each of these physical quantities is then referred to as a derived quantity, with each unit being referred to as a derived unit. The International Organization for Standardization recommends using seven base quantities, which form the International System of Quantities (ISQ).
