About Kilocalorie per Kilogram-Celsius (kcal/(kg·°C))
A metric specific-heat unit numerically identical to cal/(g·°C) — since 1 kcal/kg = 1 cal/g and 1°C = 1°C. Water's specific heat is 1 kcal/(kg·°C) by the original calorie's definition. Kcal/(kg·°C) appears in some European food science, nutrition, and older chemistry literature. Identical to cal/(g·°C), so the choice between them is purely stylistic.
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).
