How to Convert Megajoules to Watt-hours
To convert a megajoule measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One megajoule is equal to 277.777778 watt-hours, so use this simple formula to convert:
The energy in watt-hours is equal to the megajoules multiplied by 277.777778.
Megajoules and watt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
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.
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.
