How to Convert Calorie per Gram Degree Celsius to Joule per Kilogram Kelvin
- 1 cal/(g·°C) = 4186.8 J/(kg·K)
- 1 J/(kg·K) = 0.0002388458966 cal/(g·°C)
- Example: convert 1 cal/(g·°C) to J/(kg·K): 1 cal/(g·°C) = 1 × 4186.8 J/(kg·K) = 4186.8 J/(kg·K)
Reference conditions. cal/(g·°C): International Table calorie (4.1868 J).
Formula
J/(kg·K) = cal/(g·°C) × 4186.8
Derivation from SI units:
- 1 cal_IT/(g·°C) = 4.1868 J/(g·K) = 4186.8 J/(kg·K).
- Heat per unit mass per kelvin: J/(kg·K) (a kelvin step equals a degree Celsius step).
Both units are defined exactly, so the factor is exact. Calorie per Gram Degree Celsius definition: calorie per gram degree Celsius; Joule per Kilogram Kelvin definition: joule per kilogram kelvin.
Worked examples
- Water at 1 cal/(g·°C) is 4186.8 J/(kg·K).
1 cal/(g·°C) × 4186.8 = 4186.8 J/(kg·K) - Aluminium at about 0.2 cal/(g·°C) is 837.36 J/(kg·K).
0.2 cal/(g·°C) × 4186.8 = 837.36 J/(kg·K)
