  1. 1 MWh = 1000000 Wh
  2. 1 × 1000000 = 1000000 Wh

How to convert megawatt-hours to watt-hours

1 MWh = 1,000,000 Wh, so multiply by 1,000,000 to go from megawatt-hours to watt-hours. Going the other way, 1 Wh = 1 × 10⁻⁶ MWh.

Wh = MWh × 1,000,000
MWh = Wh × 1

Worked example:

1 MWh = 1000000 Wh
5 × 1000000 = 5000000 Wh
