Convert Joule per kilogram degree Celsius to Kilojoule per kilogram kelvin
Convert Joule per kilogram degree Celsius (J/(kg·°C)) to Kilojoule per kilogram kelvin (kJ/(kg·K)) instantly and accurately.
Conversion Formula
kJ/(kg·K) = J/(kg·°C) × 0.001
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 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).
