How to Convert Megajoules to Kilowatt-hours

To convert a megajoule measurement to a kilowatt-hour measurement, multiply the energy by the conversion ratio. One megajoule is equal to 0.277778 kilowatt-hours, so use this simple formula to convert:

kilowatt-hours = megajoules × 0.277778

The energy in kilowatt-hours is equal to the megajoules multiplied by 0.277778.

For example, here's how to convert 5 megajoules to kilowatt-hours using the formula above.
5 MJ = (5 × 0.277778) = 1.388889 kWh

Megajoules and kilowatt-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.

Kilowatt-hours

A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Kilowatt-hours can be abbreviated as kWh, for example 1 kilowatt-hour can be written as 1 kWh.
