Convert Joule per kilogram degree Celsius (J/(kg·°C)) to Millijoule per kilogram kelvin (mJ/(kg·K)) instantly and accurately.
Conversion Formula
mJ/(kg·K) = J/(kg·°C) × 1000
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 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).
