How to Convert Calorie per Gram Degree Celsius to Joule per Gram Kelvin
- 1 cal/(g·°C) = 4.1868 J/(g·K)
- 1 J/(g·K) = 0.2388458966 cal/(g·°C)
- Example: convert 15 cal/(g·°C) to J/(g·K): 15 cal/(g·°C) = 15 × 4.1868 J/(g·K) = 62.802 J/(g·K)
Reference conditions. cal/(g·°C): International Table calorie (4.1868 J).
Formula
J/(g·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 J/(g·K) = 1000 J/(kg·K) = 1 kJ/(kg·K).
- 1 cal/(g·°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. Calorie per Gram Degree Celsius definition: calorie per gram degree Celsius; Joule per Gram Kelvin definition: joule per gram kelvin.
Worked examples
- A reading of 0.2 cal/(g·°C) converts to 0.83736 J/(g·K).
0.2 cal/(g·°C) × 4.1868 = 0.83736 J/(g·K) - A value of 0.4 cal/(g·°C) is 1.67472 J/(g·K).
0.4 cal/(g·°C) × 4.1868 = 1.67472 J/(g·K)
