A unit is an internationally accepted standard for measurements of quantities. Every measurement has two parts. The first is a number (n) and the next is a unit (u). Q = nu.
Fundamental and Derived Quantities
The quantities that are independent of other quantities are called fundamental quantities.
The units that are used to measure these fundamental quantities are called fundamental units.
There are four systems of units namely C. G. S, M. K. S, F. P. S, and SI.
The quantities that are derived using the fundamental quantities are called derived quantities.
The units that are used to measure these derived quantities are called derived units.
Fundamental and Derived units together form a System of Units.
