About Kilojoule per kilogram degree Celsius
The kilojoule per kilogram degree Celsius (kJ/(kg·°C)) equals exactly 1 kJ/(kg·K) = 1000 J/(kg·K) since 1 °C = 1 K. The preferred notation in European process and chemical engineering where Celsius dominates. Often used interchangeably with kJ/(kg·K) in material datasheets. Water: 4.182 kJ/(kg·°C). 1 kJ/(kg·°C) = 1 kJ/(kg·K) = 1000 J/(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).
