## How to Convert Megajoules to Joules

To convert a megajoule measurement to a joule measurement, multiply the energy by the conversion ratio. One megajoule is equal to 1,000,000 joules, so use this simple formula to convert:

The energy in joules is equal to the megajoules multiplied by 1,000,000.

**For example,**here's how to convert 5 megajoules to joules using the formula above.

Megajoules and joules 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.

## Joules

The joule is the energy equal to the force on an object of one newton at a distance of one meter.^{[1]} One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*; for example, 1 joule can be written as 1 J.
