Supplementary units
The SI units radian and steradian are called supplementary units. They are `dimensionless` derived units (more precisely, derived units of dimension one) with special names and symbols. Although the coherent unit for plane angle and for solid angle is expressed by the number 1, it is convenient to use the special names radian (rad) and steradian (s.....

Derived units
Derived units are expressed algebraically in terms of base units. Their symbols are obtained by means of the mathematical signs of multiplication and division. The expression for the coherent derived units in terms of base units can be obtained from the dimensional products by using the following format substitution : L-->m, M-->kg, T-->s, I-->A, Q.....
