Question

what do you know about fundamental and derived unit

Answer 1

Derived quantities are products and/or
ratios of the fundamental quantities that
exist in a system of units . For example, the
seven fundamental quantities of the SI
system of units are length, mass, time,
electric current, temperature, amount of
substance, and luminous intensity.

Answer 2

1. Fundamental unit are those units , which can neither be derived from one another ,nor can they be further resolved into any other units.
The quantities mass,length, and the time are called fundamental physical quantities and their units are know as fundamental units.

2. The units of all such physical quantities , which can be expressed in terms of the fundamental units of mass,length,and time are called derived units.
