How to Convert Kilocalorie per Kilogram Degree Celsius to Kilojoule per Kilogram Kelvin
- 1 kcal/(kg·°C) = 4.1868 kJ/(kg·K)
- 1 kJ/(kg·K) = 0.2388458966 kcal/(kg·°C)
- Example: convert 0.92 kcal/(kg·°C) to kJ/(kg·K): 0.92 kcal/(kg·°C) = 0.92 × 4.1868 kJ/(kg·K) = 3.851856 kJ/(kg·K)
Reference conditions. kcal/(kg·°C): International Table calorie (4.1868 J).
Formula
kJ/(kg·K) = kcal/(kg·°C) × 4.1868
Derivation from SI units:
- 1 kcal_IT/(kg·°C) = 4186.8 J/(kg·K), the same number as cal/(g·°C).
- 1 kJ/(kg·K) = 1000 J/(kg·K).
- 1 kcal/(kg·°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. Kilocalorie per Kilogram Degree Celsius definition: kilocalorie per kilogram degree Celsius; Kilojoule per Kilogram Kelvin definition: kilojoule per kilogram kelvin.
Worked examples
- Ice at about 0.5 kcal/(kg·°C) is 2.0934 kJ/(kg·K).
0.5 kcal/(kg·°C) × 4.1868 = 2.0934 kJ/(kg·K) - Milk at about 0.92 kcal/(kg·°C) is 3.851856 kJ/(kg·K).
0.92 kcal/(kg·°C) × 4.1868 = 3.851856 kJ/(kg·K)
