Convert Thermochemical calorie per gram per degree Celsius to Watt-hour per kilogram kelvin
Convert Thermochemical calorie per gram per degree Celsius (cal(th)/(g·°C)) to Watt-hour per kilogram kelvin (Wh/(kg·K)) instantly and accurately.
Conversion Formula
Wh/(kg·K) = cal(th)/(g·°C) × 1.162222222
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).
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).
