## How to Convert Watt-hours to Megajoules

To convert a watt-hour measurement to a megajoule measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 0.0036 megajoules, so use this simple formula to convert:

The energy in megajoules is equal to the watt-hours multiplied by 0.0036.

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

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

## Watt-hours

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

Watt-hours can be abbreviated as *Wh*, for example 1 watt-hour can be written as 1 Wh.

## 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.
