About Calorie per Gram-Celsius (cal/(g·°C))
A CGS specific-entropy unit numerically identical to kcal/(kg·°C). Used in older chemistry literature, biological thermodynamics (protein unfolding, ligand binding), and some legacy food-science publications. Mostly superseded by SI J/(kg·K) in modern publications, but still turns up in comparative data compilations.
About Joule per Kilogram-Kelvin (J/(kg·K))
The SI unit of specific entropy — entropy per unit mass, which appears in mass-flow thermodynamic calculations (nozzle, turbine, compressor analyses). J/(kg·K) is the universal unit for reporting entropy in CFD simulations and thermodynamic state-table libraries (e.g., CoolProp, REFPROP). Same dimensional units as specific heat, but physically different quantities.
