About Millijoule per kilogram kelvin
The millijoule per kilogram kelvin (mJ/(kg·K)) equals exactly 10⁻³ J/(kg·K). Used for very light gases at extreme conditions and in precision calorimetry where tiny heat capacities must be measured. Rarely encountered in standard engineering but useful when expressing specific heat of dilute aerosols or highly rarefied media. 1 mJ/(kg·K) = 10⁻³ J/(kg·K).
About Thermochemical kilocalorie per kilogram per degree Celsius
The thermochemical kilocalorie per kilogram per degree Celsius (kcal(th)/(kg·°C)) equals exactly 4184 J/(kg·K) (1 kcal(th) = 4184 J = 1000 cal(th)). Used in older continental European and Soviet-era engineering tables as the practical metric unit. Water ≈1 kcal(th)/(kg·°C); iron ≈0.107 kcal(th)/(kg·°C). 1 kcal(th)/(kg·°C) = 4184 J/(kg·K) = 1 cal(th)/(g·°C).
