About Joule per kilogram kelvin
The joule per kilogram kelvin (J/(kg·K)) is the SI coherent unit for specific heat capacity, defined by the relation Q = mcΔT. Water ≈4182, iron ≈449, aluminium ≈897, copper ≈385, glass ≈840 J/(kg·K). Referenced in ISO 31-4 and all major international standards. 1 J/(kg·K) = 1 J/(kg·°C) = 10⁻³ kJ/(kg·K).
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).
