1 MWh = 3,600,000 kJ

Show the working
  1. 1 MWh = 3600000 kJ
  2. 1 × 3600000 = 3600000 kJ

How to convert megawatt-hours to kilojoules

1 MWh = 3,600,000 kJ, so multiply by 3,600,000 to go from megawatt-hours to kilojoules. Going the other way, 1 kJ = 2.77777777778 × 10⁻⁷ MWh.

kJ = MWh × 3,600,000
MWh = kJ × 2.77777777778

Worked example:

1 MWh = 3600000 kJ
5 × 3600000 = 18000000 kJ
