About International table kilocalorie per kilogram per degree Celsius
The international table kilocalorie per kilogram per degree Celsius (kcal(IT)/(kg·°C)) equals exactly 4186.8 J/(kg·K) (1 kcal(IT) = 4186.8 J). The common practical unit in European industry and the 'large calorie' of nutrition science. Water: 1 kcal(IT)/(kg·°C); ethanol: 0.588 kcal(IT)/(kg·°C). 1 kcal(IT)/(kg·°C) = 4186.8 J/(kg·K) = 1 cal(IT)/(g·°C).
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).
