To convert watt-hours to megajoules, enter the value in the first field. The result in megajoules is calculated automatically using the exact conversion factor.

1 Wh = 0.0036 MJ
1 MJ ≈ 277.777777778 Wh

Formula: MJ = Wh × 0.0036
Wh ≈ MJ × 277.777777778

Definitions: 1 Wh = 3600 J; 1 MJ = 1000000 J

The watt-hour (Wh) is the energy of one watt working for one hour, exactly 3,600 joules. It is used for the capacity of phone, laptop and power bank batteries and for small amounts of electricity.

The megajoule (MJ) is one million joules. It is used for the energy content of fuels and for heating and gas measurements, and one kilowatt-hour equals 3.6 MJ.
