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).
About Watt-hour per kilogram kelvin
The watt-hour per kilogram kelvin (Wh/(kg·K)) equals exactly 3600 J/(kg·K). Used in battery and thermal energy storage engineering to express the heat capacity of phase-change materials (PCM), molten salts, and battery cells where energy is quantified in watt-hours. Paraffin wax ≈0.055 Wh/(kg·K). 1 Wh/(kg·K) = 3600 J/(kg·K) = 3.6 kJ/(kg·K).
