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 Mostly superseded by SI J/(kg·K) in modern publications, but still turns up in comparative data compilations.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 BTU per Pound-Rankine (BTU/(lb·°R))
An imperial specific-entropy unit dominant in US steam tables and thermodynamics textbooks. 1 BTU/(lb·°R) ≈ 4,186.8 J/(kg·K) — numerically identical to the J/(kg·K) value (since BTU/lb/°R and kJ/kg/K convert with a near-unity factor). US-edition NIST steam tables and ASME thermodynamic references list entropy in BTU/(lb·°R).
