About Joule per kilogram degree Celsius
The joule per kilogram degree Celsius (J/(kg·°C)) equals exactly 1 J/(kg·K) since temperature intervals 1 °C = 1 K. Widely used in building physics, HVAC, and thermodynamics textbooks where Celsius is the standard temperature scale. Material property tables in ISO and EN standards frequently list specific heat in J/(kg·°C). 1 J/(kg·°C) = 1 J/(kg·K).
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).
