How to Convert Kilowatt-hours to Megajoules

To convert a kilowatt-hour measurement to a megajoule measurement, multiply the energy by the conversion ratio. One kilowatt-hour is equal to 3.6 megajoules, so use this simple formula to convert:

megajoules = kilowatt-hours × 3.6

The energy in megajoules is equal to the kilowatt-hours multiplied by 3.6.

For example, here's how to convert 5 kilowatt-hours to megajoules using the formula above.
5 kWh = (5 × 3.6) = 18 MJ

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

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.

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.
