A derived quantity is a quantity that is based on the result of a systematic equation that includes any of the seven basic quantities, which are the kilogram, meter, second, ampere, kelvin, mole and candela. Examples of derived quantities include area (square meters), speed (meters per second) and frequency (hertz).
A small number of base quantities that are assumed to be independent are chosen from the system of quantities such that any other quantity of the system, called a derived quantity, can be expressed as a function of the base quantities.
Alright , if you want to understand the concept of derived quantities , we must go step by step . So first of all : PHYSICAL QUANTITIES : “All the measurable quantities are called physical quantities.” Every physical quantity consists of two thing...
The SI has special names for 22 of these derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m 2), the SI derived unit of area; and the kilogram per cubic metre (kg/m 3 or kg⋅m −3), the SI derived unit of density.
All other quantities are expressed in terms of these quantities. Derived Physical Quantities. When a physical quantity expresses itself in terms of two or more fundamental physical quantities. It is derived by multiplying or dividing one basic physical quantity with another basic physical quantity.
The quantities that do not depend on any other physical quantity for their measurement are known as fundamental quantities. These quantities do not take support of other physical quantities for its measurement. There are only 7 fundamental physical quantities. And rest of all other quantities are derived quantities. They are listed below.

Base Quantity and Derived Quantity (Reviewed and updated on 30/05/2016) ... Derived quantities are physical quantities which are derived from the base quantities by multiplication or division or both. For example, speed is a derived quantity of length (distance travelled) over time.

Derived Quantity. A derived quantity is defined based on a combination of base quantities and has a derived unit that is the exponent, product or quotient of these base units. Note: Units, such as the joule, newton, volt and ohm, are SI units, but they are not base SI units.
