How to convert megawatt-hours to kilowatt-hours

1 megawatt-hour = 1,000 kilowatt-hours. To convert megawatt-hours to kilowatt-hours, multiply by 1,000. A megawatt-hour is 1,000 kilowatt-hours, exactly 3.6 billion joules. A kilowatt-hour is the energy of 1 kW running for one hour, exactly 3.6 million joules.

Worked examples

  • 1 megawatt-hour = 1,000 kWh (1 × 1,000)
  • 10.5 megawatt-hours = 10,500 kWh (10.5 × 1,000)
  • 250 megawatt-hours = 250,000 kWh (250 × 1,000)

Where this conversion comes up

Megawatt-hours are used for power plant output, utility-scale batteries and industrial electricity use; kilowatt-hours for electricity bills, home batteries and EV charging. Utilities, solar farms and energy contracts quote megawatt-hours, while your bill is in kilowatt-hours. 1 MWh is exactly 1,000 kWh, a little over a month of electricity for an average US home (roughly 10,000 to 11,000 kWh a year per the EIA). Do not mix up MWh (energy) with MW (power): a 1 MW solar plant running at full output for one hour makes 1 MWh.

Quick estimate

Multiply by 1,000, or move the decimal point three places right: 2.5 MWh = 2,500 kWh.

Common mistakes

  • Dividing instead of multiplying. A kilowatt-hour is smaller than a megawatt-hour, so the number of kilowatt-hours must come out larger: 1 megawatt-hour = 1,000 kWh.
