# Megajoules to Watt-seconds Conversion

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

Results in Watt-seconds: 1 MJ = 1,000,000 Ws

## How to Convert Megajoules to Watt-seconds

To convert a megajoule measurement to a watt-second measurement, multiply the energy by the conversion ratio. One megajoule is equal to 1,000,000 watt-seconds, so use this simple formula to convert:

watt-seconds = megajoules × 1,000,000

The energy in watt-seconds is equal to the megajoules multiplied by 1,000,000.

For example, here's how to convert 5 megajoules to watt-seconds using the formula above.
5 MJ = (5 × 1,000,000) = 5,000,000 Ws

## Megajoules

One megajoule is equal to 1,000,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.

The megajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "mega" is the prefix for 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.

## 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.

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.
