A megawatt hour (MWh) is a unit of energy. It is a measure of the actual amount of power consumed or produced by one megawatt expended for a period of one hour. A megawatt (MW) is a unit of power. It describes the rate at which power is being consumed or produced by a circuit at any given moment in time. A megawatt is equivalent to one million watts.

The formula used to calculate megawatt-hours is Megawatt hours (MWh) = Megawatts (MW) x Hours (h).

To convert megawatt hours to megawatts, you are going to need to divide the number of megawatt hours by the number of hours. In other words: Megawatts (MW) = Megawatt hours (MWh) / Hours (h).

## Step 1

Determine the number of megawatt hours.

## Step 2

Determine the number of hours. (To convert megawatt hours to megawatts, the number of hours must also be known.)

## Step 3

Divide the number of megawatt hours by the number of hours. The resulting number is the number of megawatts.
