How to Convert Kilojoule per Kilogram Kelvin to Kilocalorie per Kilogram Degree Celsius
- 1 kJ/(kg·K) = 0.2388458966 kcal/(kg·°C)
- 1 kcal/(kg·°C) = 4.1868 kJ/(kg·K)
- Example: convert 15 kJ/(kg·K) to kcal/(kg·°C): 15 kJ/(kg·K) = 15 × 0.2388458966 kcal/(kg·°C) = 3.582688449 kcal/(kg·°C)
Reference conditions. kcal/(kg·°C): International Table calorie (4.1868 J).
Formula
kcal/(kg·°C) = kJ/(kg·K) × 0.2388458966275
or kcal/(kg·°C) = kJ/(kg·K) ÷ 4.1868
Derivation from SI units:
- 1 kJ/(kg·K) = 1000 J/(kg·K).
- 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) ÷ 4186.8 J/(kg·K) per kcal/(kg·°C) = 0.2388458966275 kcal/(kg·°C)
Both units are defined exactly, so the factor is exact. Kilojoule per Kilogram Kelvin definition: kilojoule per kilogram kelvin; Kilocalorie per Kilogram Degree Celsius definition: kilocalorie per kilogram degree Celsius.
Worked examples
- A reading of 0.84 kJ/(kg·K) converts to 0.2006305532 kcal/(kg·°C).
0.84 kJ/(kg·K) × 0.2388458966 = 0.2006305532 kcal/(kg·°C) - A value of 1.7 kJ/(kg·K) is 0.4060380243 kcal/(kg·°C).
1.7 kJ/(kg·K) × 0.2388458966 = 0.4060380243 kcal/(kg·°C)
