Convert International table calorie per gram per degree Celsius to Kilojoule per kilogram kelvin
Convert International table calorie per gram per degree Celsius (cal(IT)/(g·°C)) to Kilojoule per kilogram kelvin (kJ/(kg·K)) instantly and accurately.
Conversion Formula
kJ/(kg·K) = cal(IT)/(g·°C) × 4.1868
About International table calorie per gram per degree Celsius
The international table calorie per gram per degree Celsius (cal(IT)/(g·°C)) equals exactly 4186.8 J/(kg·K) (1 cal(IT) = 4.1868 J). Standard in steam tables, international thermodynamic references, and pre-SI calorimetry. Slightly larger than the thermochemical variant. Water: 1 cal(IT)/(g·°C) at ≈15 °C. 1 cal(IT)/(g·°C) = 4186.8 J/(kg·K) = 1 kcal(IT)/(kg·°C).
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).
