Megawatt Converters

Convert megawatts to watts, kilowatts, gigawatts, horsepower, BTU per hour and other power units.

What this tool does

Convert megawatts to watts, kilowatts, gigawatts, horsepower, BTU per hour and other power units. Type an amount in megawatts, choose the units, and the tool converts it to watts. It offers 11 power units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 11 options, including Megawatt, Gigawatt, Kilowatt, Watt, Horsepower (mechanical, 550 ft·lbf/s), Horsepower (metric, PS). Starts as Megawatt.
  • To: Choose one of the same 11 units as "From". Starts as Watt.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from megawatts to watts:

  • 1 MW = 1,000,000 W
  • 5 MW = 5,000,000 W
  • 10 MW = 10,000,000 W
  • 50 MW = 50,000,000 W
  • 100 MW = 100,000,000 W

Multiply the number of megawatts by 1,000,000 to get watts. Both units are exact definitions, so 1,000,000 is the exact factor: 1 MW = 1,000,000 W.

Limitations

  • Converts units of power only. Megawatts are not megawatt-hours; use an energy converter for those.
  • Horsepower is shown as mechanical and metric.
  • BTU means the International Table BTU. Calories per second are thermochemical calories; kilocalories per hour are International Table.
