Hint: The SI system of the unit measurement is the internationally accepted system of unit measurement. This system is accepted world-wide to avoid the miscommunication of scientific data.
Complete step-by-step answer:
The physical quantities are the quantities that are the base quantities of the measurement. They are known as the fundamental quantities. The units of those units are known as the fundamental units.
The derived physical quantities are dependent on the fundamental quantities. The units of those quantities are known as the derived units.
Note: There is one more unit other than the fundamental and derived units, this is the supplementary units. The supplementary units are the dimensionless units. There are two supplementary quantities: angle and solid angle. The unit of these two quantities is radians and the steradians.
