About these units
The kilowatt-hour per kilogram (kWh/kg) is a metric unit of specific energy, equal to 3,600,000 joules per kilogram.
The megajoule per kilogram (MJ/kg) is a metric unit of specific energy, equal to 1,000,000 joules per kilogram.
Going the other way, 1 megajoule per kilogram = 0.27777778 kilowatt-hours per kilogram. Specific energy is energy per unit mass. It is how battery cells are compared, typically 150 to 300 Wh/kg for lithium-ion, and how fuels are rated, with diesel near 45 MJ/kg. Convert between the battery, fuel and food-energy units.
