Convert Calories per Gram Degree Celsius to kJ/(kg·K)
1 calorie per gram degree Celsius (cal/(g·°C)) = 4.1868 kilojoules per kilogram kelvin (kJ/(kg·K)). 1 kJ/(kg·K) = 0.2388458966 cal/(g·°C). Example: 15 cal/(g·°C) = 15 × 4.1868 = 62.802 kJ/(kg·K).

How to Convert Calorie per Gram Degree Celsius to Kilojoule per Kilogram Kelvin
- 1 cal/(g·°C) = 4.1868 kJ/(kg·K)
- 1 kJ/(kg·K) = 0.2388458966 cal/(g·°C)
- Example: convert 15 cal/(g·°C) to kJ/(kg·K): 15 cal/(g·°C) = 15 × 4.1868 kJ/(kg·K) = 62.802 kJ/(kg·K)
Reference conditions. cal/(g·°C): International Table calorie (4.1868 J).
Formula
kJ/(kg·K) = cal/(g·°C) × 4.1868
Derivation from SI units:
- 1 cal_IT/(g·°C) = 4.1868 J/(g·K) = 4186.8 J/(kg·K).
- 1 kJ/(kg·K) = 1000 J/(kg·K).
- 1 cal/(g·°C) = 4186.8 J/(kg·K) ÷ 1000 J/(kg·K) per kJ/(kg·K) = 4.1868 kJ/(kg·K)
Both units are defined exactly, so the factor is exact. Calorie per Gram Degree Celsius definition: calorie per gram degree Celsius; Kilojoule per Kilogram Kelvin definition: kilojoule per kilogram kelvin.
Worked examples
- A reading of 0.2 cal/(g·°C) converts to 0.83736 kJ/(kg·K).
0.2 cal/(g·°C) × 4.1868 = 0.83736 kJ/(kg·K) - A value of 0.4 cal/(g·°C) is 1.67472 kJ/(kg·K).
0.4 cal/(g·°C) × 4.1868 = 1.67472 kJ/(kg·K)
