1 MWh = 1,000 kWh

Show the working
  1. 1 MWh = 1000 kWh
  2. 1 × 1000 = 1000 kWh

How to convert megawatt-hours to kilowatt-hours

1 MWh = 1,000 kWh, so multiply by 1,000 to go from megawatt-hours to kilowatt-hours. Going the other way, 1 kWh = 0.001 MWh.

kWh = MWh × 1,000
MWh = kWh × 0.001

Worked example:

1 MWh = 1000 kWh
5 × 1000 = 5000 kWh
