About these units
The watt-hour per kilogram (Wh/kg) is a metric unit of specific energy, equal to 3,600 joules per kilogram.
The joule per kilogram (J/kg) is an SI base or derived unit of specific energy.
Going the other way, 1 joule per kilogram = 0.00027777778 watt-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.
