## 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:

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.

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 10^{6}. 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 are usually abbreviated as *kWh*, although the formally adopted expression is *kW·h*. The abbreviation *kW h* is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.^{[1]}
