  8. In 1995, the General Conference on Weights and Measures decided to eliminate the class of SI supplementary units as a separate class in the SI and to interpret the units ‘radian’ and ‘steradian’ as dimensionless SI derived units, the names and symbols of which may, but need not, be used in expressions for other SI derived units, as is convenient.
