## How to Convert Watt-Hours to Megawatt-Hours

To convert a measurement in watt-hours to a measurement in megawatt-hours, divide the energy by the following conversion ratio: 1,000,000 watt-hours/megawatt-hour.

Since one megawatt-hour is equal to 1,000,000 watt-hours, you can use this simple formula to convert:

megawatt-hours = watt-hours ÷ 1,000,000

The energy in megawatt-hours is equal to the energy in watt-hours divided by 1,000,000.

**For example,**here's how to convert 500,000 watt-hours to megawatt-hours using the formula above.

Watt-hours and megawatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.

## What Is a Watt-Hour?

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours are usually abbreviated as *Wh*, although the formally adopted expression is *W·h*. The abbreviation *W h* is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.^{[1]}

## What Is a Megawatt-Hour?

A megawatt-hour is a measure of electrical energy equal to one megawatt, or 1,000,000 watts, of power over a one hour period. Megawatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Megawatt-hours are usually abbreviated as *MWh*, although the formally adopted expression is *MW·h*. The abbreviation *MW h* is also sometimes used. For example, 1 megawatt-hour can be written as 1 MWh, 1 MW·h, or 1 MW h.
