Introduction of Units and Measurements
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.
