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:

megajoules = watt-hours × 0.0036

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

For example, here's how to convert 5 watt-hours to megajoules using the formula above.
5 Wh = (5 × 0.0036) = 0.018 MJ

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 109. Megajoules can be abbreviated as MJ, for example 1 megajoule can be written as 1 MJ.
