About Kilojoule per kilogram kelvin
The kilojoule per kilogram kelvin (kJ/(kg·K)) equals exactly 1000 J/(kg·K). The most common unit in engineering thermodynamics textbooks and technical data sheets: water ≈4.182, steam ≈2.08, dry air ≈1.005 kJ/(kg·K). Found throughout ASHRAE, ISO, and EN standards for heat exchanger and HVAC design. 1 kJ/(kg·K) = 1000 J/(kg·K) = 1 kJ/(kg·°C).
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).
