Independent of the temperature that the Bunsen coefficient refers to, 273.15 K is always used for the conversion . The Bunsen coefficient, which is named after Robert Bunsen, has been used mainly in the older literature . </P> <P> According to Sazonov and Shaw, the Kuenen coefficient S (\ displaystyle S) is defined as "the volume of saturating gas V (g), reduced to T ° = 273.15 K, p ° = bar, which is dissolved by unit mass of pure solvent at the temperature of measurement and partial pressure 1 bar ."
