## How to Convert Watt-seconds to Megajoules

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

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

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

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

## 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.^{[1]}

## 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 10^{6}. Megajoules can be abbreviated as *MJ*, for example 1 megajoule can be written as 1 MJ.
