decides to add:

wave number 1 per metre m–1
entropy joule per kelvin J/K
specific heat capacity joule per kilogram kelvin J/(kg × K)
thermal conductivity watt per metre kelvin W/(m × K)
radiant intensity watt per steradian W/sr
activity (of a radioactive source) 1 per second s–1

reference The reader should note that the official version of this Resolution is the French text

NOTE

The unit of activity was given a special name and symbol by the 15th CGPM in 1975 (Resolution 8).
