About Calorie per Gram-Celsius (cal/(g·°C))
A CGS specific-heat unit historically used in chemistry and food science. By the original definition of the calorie, water has a specific heat of exactly 1 cal/(g·°C) — the basis on which both the unit and the property coevolved. Numerically identical to kcal/(kg·°C). Chemistry textbooks and nutrition science papers from the 20th century frequently reported specific heats in this unit, and calorimetry experiments in education still use it.
About Kilojoule per Kilogram-Kelvin (kJ/(kg·K))
A metric specific-heat unit equal to 1,000 J/(kg·K). Because most common substances have specific heats in the 0.3–5 kJ/(kg·K) range, many European and international thermodynamics textbooks default to kJ/(kg·K) to keep numbers human-readable. Water is 4.186 kJ/(kg·K); steel ~0.49 kJ/(kg·K); liquid nitrogen ~1.04 kJ/(kg·K). Steam tables and refrigerant property tables typically list values in kJ/(kg·K).
