About Kilojoule per kilogram degree Celsius
The kilojoule per kilogram degree Celsius (kJ/(kg·°C)) equals exactly 1 kJ/(kg·K) = 1000 J/(kg·K) since 1 °C = 1 K. The preferred notation in European process and chemical engineering where Celsius dominates. Often used interchangeably with kJ/(kg·K) in material datasheets. Water: 4.182 kJ/(kg·°C). 1 kJ/(kg·°C) = 1 kJ/(kg·K) = 1000 J/(kg·K).
About International table BTU per pound per degree Fahrenheit
The international table BTU per pound per degree Fahrenheit (BTU(IT)/(lb·°F)) equals (1055.05585262 × 9)/(0.45359237 × 5) J/(kg·K) = 4186.8 J/(kg·K). The standard US unit for specific heat capacity in ASHRAE, ASTM, and mechanical engineering references. Water: 1.000 BTU(IT)/(lb·°F); steel: ≈0.108; air: ≈0.240. 1 BTU(IT)/(lb·°F) = 4186.8 J/(kg·K).
