Convert Thermochemical kilocalorie per kilogram per degree Celsius (kcal(th)/(kg·°C)) to Kilojoule per kilogram kelvin (kJ/(kg·K)) instantly and accurately.
Conversion Formula
kJ/(kg·K) = kcal(th)/(kg·°C) × 4.184
About Thermochemical kilocalorie per kilogram per degree Celsius
The thermochemical kilocalorie per kilogram per degree Celsius (kcal(th)/(kg·°C)) equals exactly 4184 J/(kg·K) (1 kcal(th) = 4184 J = 1000 cal(th)). Used in older continental European and Soviet-era engineering tables as the practical metric unit. Water ≈1 kcal(th)/(kg·°C); iron ≈0.107 kcal(th)/(kg·°C). 1 kcal(th)/(kg·°C) = 4184 J/(kg·K) = 1 cal(th)/(g·°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).
