Calories per gram-°C to joules per kilogram-kelvin
Type a value in cal/(g·°C) to get it in J/(kg·K) instantly.
4,184,000J/(kg·K)
That's 1,000× as much heat as water — nothing on our list beats it. Warming one kilogram by 10 °C takes about 41,840,000 J.
Convert the other way: J/(kg·K) to cal/(g·°C)
What it means
How much heat does it hold?
Values are at room temperature and constant pressure. Gases differ between constant pressure and constant volume.
The math
How to convert cal/(g·°C) to J/(kg·K)
To convert calories per gram-°C to joules per kilogram-kelvin, multiply by 4,184.
Example: 1,000 cal/(g·°C) × 4,184 = 4,184,000 J/(kg·K).
In the other direction, 1 J/(kg·K) = 0.000239006 cal/(g·°C).
