# Megawatt-hours to Watt-hours Conversion

Enter the energy in megawatt-hours below to get the value converted to watt-hours.

Results in Watt-hours: 1 MWh = 1,000,000 Wh

## How to Convert Megawatt-hours to Watt-hours

To convert a megawatt-hour measurement to a watt-hour measurement, multiply the energy by the conversion ratio.

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

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

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

For example, here's how to convert 5 megawatt-hours to watt-hours using the formula above.
5 MWh = (5 × 1,000,000) = 5,000,000 Wh ### How Many Watt-hours Are in a Megawatt-hour?

There are 1,000,000 watt-hours in a megawatt-hour, which is why we use this value in the formula above.

1 MWh = 1,000,000 Wh

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

## Megawatt-hours

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.

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.

## Watt-hours

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.
