Specific latent heatexact by definition
The kilowatt-hour per kilogram is exactly 3.6 × 10⁶ J/kg, or 3.6 MJ/kg. It is the convenient scale for fuels compared against electricity: gasoline is about 12.9 kW·h/kg, which is why the energy density argument in transport is not close and the efficiency argument is.
