About Calorie per Kelvin (cal/K)
A CGS entropy unit (1 cal/K = 4.184 J/K) that appears in legacy chemistry and biochemistry literature. Standard entropies of biomolecules, reaction entropy changes, and protein-folding entropy are still occasionally reported in cal/(K·mol) or cal/K in older or specific-field papers.
About Joule per Kelvin (J/K)
The SI unit of entropy — the thermodynamic state function that measures disorder or the spread of energy among microstates. J/K is the universal unit in thermodynamics, statistical mechanics, and information-theory analogies. The second law of thermodynamics (ΔS ≥ 0 for isolated systems) is formalized in J/K. Reference values are tabulated in thermodynamic-property tables for every common substance.
