About Kilojoule per Kelvin (kJ/K)
A metric entropy unit equal to 1,000 J/K. Used at industrial/plant scale: steam-turbine cycle analysis, refrigeration-cycle second-law evaluations, and large-scale combustion entropy balances. Power-plant heat-balance diagrams often express entropy flows in kJ/K for readability.
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.
