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.
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 K interval = 1 °C interval. Water's specific heat is exactly 1 kcal/(kg·°C) by the original 'large calorie' (= kilocalorie) definition. kcal/(kg·°C) appears in European food-science literature (calorimetry data in EU FOSS / Codex Alimentarius food-composition databases), pre-2000 European HVAC and process-engineering documentation (especially German DIN-era specs that haven't migrated fully to J/(kg·K)), nutrition-science papers reporting metabolic-rate calculations against the 1 kcal/(kg·°C) water baseline, and older chemistry literature from Eastern Europe and Russia. The choice between cal/(g·°C) and kcal/(kg·°C) is purely a matter of which mass scale is convenient — they encode the same physical quantity with the same numerical value. Convert kcal/(kg·°C) to J/(kg·K) by multiplying by 4,184; to BTU/(lb·°F) by dividing by 1.
