About Kilojoule per Kilogram-Kelvin (kJ/(kg·K))
A metric specific-heat unit equal to exactly 1,000 J/(kg·K). Because most common substances have specific heats in the 0.3-5 kJ/(kg·K) range, kJ/(kg·K) is the default working unit on every published thermodynamic property table (IAPWS-IF97 steam tables, NIST REFPROP refrigerant data, NASA CEA gas-property tables, Çengel-Boles 'Thermodynamics: An Engineering Approach' textbook, Moran-Shapiro 'Fundamentals of Engineering Thermodynamics'). Reference values: water at 25 °C is 4.186 kJ/(kg·K); structural steel ~0.49 kJ/(kg·K); aluminum 0.897 kJ/(kg·K); liquid nitrogen at saturation ~1.04 kJ/(kg·K); R-134a refrigerant vapour ~1.0 kJ/(kg·K) at saturation; R-1234yf (low-GWP automotive refrigerant) ~0.95 kJ/(kg·K). For ideal-gas calculations: dry air cp = 1.005 kJ/(kg·K), cv = 0.718 kJ/(kg·K), with ratio γ = cp/cv = 1.4 used in compressible-flow analysis. Steam tables in Çengel-Boles default to kJ/(kg·K) for both cp and cv.
About Joule per Kilogram-Kelvin (J/(kg·K))
The SI unit of specific heat capacity (ISO 80000-5 §5-15) — the energy required to raise the temperature of one kilogram of material by exactly one kelvin (= one degree Celsius, since the K and °C have identical interval sizes). J/(kg·K) is the universal working unit in thermodynamics, heat-transfer analysis, calorimetry, materials thermal characterization, and CFD/thermal simulation (Ansys Mechanical Thermal, COMSOL Heat Transfer Module, ABAQUS Standard all use J/(kg·K) internally). Reference values per CRC Handbook + NIST WebBook: water 4,186 J/(kg·K) at 25 °C — the highest of any common substance and the reason water is the universal thermal-storage medium; ice 2,090 J/(kg·K); water vapour 1,996 J/(kg·K); dry air at 25 °C 1,005 J/(kg·K) (cp); ethanol 2,440 J/(kg·K); helium gas 5,193 J/(kg·K) (the highest of common gases due to its very low molecular mass); iron 449 J/(kg·K); aluminum 897 J/(kg·K); copper 385 J/(kg·K); concrete 880 J/(kg·K); typical engineering polymer 1,000-2,000 J/(kg·K). Convert J/(kg·K) to kJ/(kg·K) by dividing by 1,000; to BTU/(lb·°F) by dividing by 4,186.8; to cal/(g·°C) by dividing by 4,184.
