About the units
Kilowatt-hour per kilogram (kWh/kg)
The kilowatt-hour per kilogram (kWh/kg) is a unit of fuel efficiency by mass in the metric system. One kilowatt-hour per kilogram equals 3,600,000 joules per kilogram (J/kg).
Megajoule per kilogram (MJ/kg)
The megajoule per kilogram (MJ/kg) is a unit of fuel efficiency by mass in the International System of Units (SI). One megajoule per kilogram equals 1,000,000 joules per kilogram (J/kg).
Frequently asked questions
How many megajoules per kilogram are in one kilowatt-hour per kilogram?
There are 3.6 megajoules per kilogram in one kilowatt-hour per kilogram, and this value is exact by definition.
How do I convert kilowatt-hours per kilogram to megajoules per kilogram?
Multiply the number of kilowatt-hours per kilogram by 3.6. For example, 10 kWh/kg × 3.6 = 36 MJ/kg.
How many kilowatt-hours per kilogram are in one megajoule per kilogram?
