About Joule per Kilogram-Kelvin (J/(kg·K))
The SI unit of specific heat capacity — the energy needed to raise the temperature of 1 kg of material by 1 K. J/(kg·K) is the universal unit in thermodynamics and heat-transfer analysis. Water's specific heat, the highest of any common substance, is 4,186 J/(kg·K); air is about 1,005 J/(kg·K); most metals are 400–900 J/(kg·K). Every CFD solver, HVAC sizing tool, and thermal-mass calculation uses J/(kg·K) internally.
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.
