How to Convert Kilocalorie per Kilogram Degree Celsius to Joule per Gram Kelvin
- 1 kcal/(kg·°C) = 4.1868 J/(g·K)
- 1 J/(g·K) = 0.2388458966 kcal/(kg·°C)
- Example: convert 15 kcal/(kg·°C) to J/(g·K): 15 kcal/(kg·°C) = 15 × 4.1868 J/(g·K) = 62.802 J/(g·K)
Reference conditions. kcal/(kg·°C): International Table calorie (4.1868 J).
Formula
J/(g·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 J/(g·K) = 1000 J/(kg·K) = 1 kJ/(kg·K).
- 1 kcal/(kg·°C) = 4186.8 J/(kg·K) ÷ 1000 J/(kg·K) per J/(g·K) = 4.1868 J/(g·K)
Both units are defined exactly, so the factor is exact. Kilocalorie per Kilogram Degree Celsius definition: kilocalorie per kilogram degree Celsius; Joule per Gram Kelvin definition: joule per gram kelvin.
Worked examples
- A reading of 0.2 kcal/(kg·°C) converts to 0.83736 J/(g·K).
0.2 kcal/(kg·°C) × 4.1868 = 0.83736 J/(g·K) - A value of 0.5 kcal/(kg·°C) is 2.0934 J/(g·K).
0.5 kcal/(kg·°C) × 4.1868 = 2.0934 J/(g·K)
