Kilojoules per kilogram to kilocalories per kilogram
Type a value in kJ/kg to get it in kcal/kg instantly.
539.4kcal/kg
That's about the same as boiling water. A 2 kW kettle would need about 1,129 seconds to supply that for one kilogram.
Convert the other way: kcal/kg to kJ/kg
What it means
How much energy is that?
Latent heat is quoted at the transition temperature and pressure. Water’s 2,257 kJ/kg is at 100 °C; at 20 °C evaporation costs about 2,450.
The math
How to convert kJ/kg to kcal/kg
To convert kilojoules per kilogram to kilocalories per kilogram, multiply by 0.239006.
Example: 2,257 kJ/kg × 0.239006 = 539.436 kcal/kg.
In the other direction, 1 kcal/kg = 4.184 kJ/kg.
