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 Thermochemical calorie per gram per degree Celsius
The thermochemical calorie per gram per degree Celsius (cal(th)/(g·°C)) equals exactly 4184 J/(kg·K) (1 cal(th) = 4.184 J). The CGS unit of specific heat dominant in older US chemistry and biochemistry. Liquid water has a specific heat of almost exactly 1 cal(th)/(g·°C). Slightly smaller than the IT counterpart. 1 cal(th)/(g·°C) = 4184 J/(kg·K) = 1 kcal(th)/(kg·°C).
