Convert Watt-hour per kilogram kelvin to Millijoule per kilogram kelvin
Convert Watt-hour per kilogram kelvin (Wh/(kg·K)) to Millijoule per kilogram kelvin (mJ/(kg·K)) instantly and accurately.
Conversion Formula
mJ/(kg·K) = Wh/(kg·K) × 3600000
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).
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).
