Convert Thermochemical calorie per gram per degree Celsius to Kilojoule per kilogram kelvin
Convert Thermochemical calorie per gram per degree Celsius (cal(th)/(g·°C)) to Kilojoule per kilogram kelvin (kJ/(kg·K)) instantly and accurately.
Conversion Formula
kJ/(kg·K) = cal(th)/(g·°C) × 4.184
About Thermochemical calorie per gram per degree Celsius
The thermochemical calorie per gram per degree Celsius (cal(th)/(g·°C)) equals exactly 4184 J/(kg·K) (1 cal(th) = 4.184 J). The CGS unit of specific heat dominant in older US chemistry and biochemistry. Liquid water has a specific heat of almost exactly 1 cal(th)/(g·°C). Slightly smaller than the IT counterpart. 1 cal(th)/(g·°C) = 4184 J/(kg·K) = 1 kcal(th)/(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).
