A base quantity is a physical quantity that cannot be derived from other physical quantities.
Example : -length (m)
-mass (kg)
-time (s)
-temperature (Kelvin)
-electric current (Ampere)

A derived quantity is a physical quantity that can be calculated or expressed in terms of base quantity.
Example : - area
-volume
-density
-velocity
-acceleration
-work
-power
