How to Convert Kilowatt-Hours to Megawatts

Updated November 21, 2016

Electricity can be measured in wattage, or the rate at which power is used at a given moment. Just as 1,000 meters equals one kilometre, 1,000 watts is equal to 1 kilowatt (kW). One thousand kW equal one megawatt (MW). Electric companies charge by the kilowatt-hour (kWh), which is how many thousands of watts you are using each hour. If you know the hours of usage, you can calculate MW from kWh with some simple math.

Calculate megawatt-hours (MWh) from kWh. Multiply kWh by 0.001 or divide kWh by 1,000.

Calculate MW from MWh. Divide MWh by the hours of usage.

Record the number in step 2. This is your total MW.

Things You'll Need

  • Calculator or pencil and paper
  • Hours of usage
