How many supplementary fundamental units are there in the SI system?a)...
In the SI system, there are two supplementary fundamental units: the Radian (rad) for plane angle and the Steradian (sr) for solid angle. These units supplement the seven base fundamental quantities to provide a comprehensive framework for measuring various physical quantities accurately. Understanding these supplementary units is essential for precise calculations and measurements in fields that require angular considerations.

How many supplementary fundamental units are there in the SI system?a)...
Understanding SI Units
The International System of Units (SI) is a standardized system used globally for scientific measurements. Within this system, there are fundamental units and supplementary units.
Fundamental Units in SI
The SI system consists of seven fundamental units which are:
- Meter (m) for length
- Kilogram (kg) for mass
- Second (s) for time
- Ampere (A) for electric current
- Kelvin (K) for temperature
- Mole (mol) for the amount of substance
- Candela (cd) for luminous intensity
Supplementary Units
The SI system previously categorized certain units as supplementary. However, the current understanding is that these supplementary units have been integrated into the fundamental units.
Count of Supplementary Units
In the revised SI system, there are only two supplementary units recognized:
- Radian (rad) for angle
- Steradian (sr) for solid angle
These units are dimensionless but are essential for expressing angles in scientific contexts.
Conclusion
Thus, the correct answer to the question of how many supplementary fundamental units there are in the SI system is indeed two. This reflects the evolution of the SI system, where clarity and consistency have led to the reclassification of certain units. By understanding the distinction between fundamental and supplementary units, one can better grasp the structure of measurements in science and engineering.
