Megajoules per kilogram to kilojoules per kilogram
Type a value in MJ/kg to get it in kJ/kg instantly.
2,257,000kJ/kg
That's 1,000× as much as boiling water — nothing on our list beats it. A 2 kW kettle would need about 1,129,000 seconds to supply that for one kilogram.
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 MJ/kg to kJ/kg
To convert megajoules per kilogram to kilojoules per kilogram, multiply by 1,000.
Example: 2,257 MJ/kg × 1,000 = 2,257,000 kJ/kg.
In the other direction, 1 kJ/kg = 0.001 MJ/kg.
