# Megawatt-hours to Watt-seconds Conversion

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

Results in Watt-seconds: 1 MWh = 3,600,000,000 Ws

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

To convert a megawatt-hour measurement to a watt-second measurement, multiply the energy by the conversion ratio. One megawatt-hour is equal to 3,600,000,000 watt-seconds, so use this simple formula to convert:

watt-seconds = megawatt-hours × 3,600,000,000

The energy in watt-seconds is equal to the megawatt-hours multiplied by 3,600,000,000.

For example, here's how to convert 5 megawatt-hours to watt-seconds using the formula above.
5 MWh = (5 × 3,600,000,000) = 18,000,000,000 Ws

## 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-seconds

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds are usually abbreviated as Ws, although the formally adopted expression is W·s. The abbreviation W s is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.
