## How to Convert Megajoules to Joules

To convert a measurement in megajoules to a measurement in joules, multiply the energy by the following conversion ratio: 1,000,000 joules/megajoule.

Since one megajoule is equal to 1,000,000 joules, you can use this simple formula to convert:

joules = megajoules × 1,000,000

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

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

### How Many Joules Are in a Megajoule?

There are **1,000,000** joules in a megajoule, which is why we use this value in the formula above.

1 MJ = 1,000,000 J

Megajoules and joules are both units used to measure energy. Keep reading to learn more about each unit of measure.

## What Is a Megajoule?

One megajoule is equal to 1,000,000 joules, which is 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 millions, or 10^{6}. Megajoules can be abbreviated as *MJ*; for example, 1 megajoule can be written as 1 MJ.

## What Is a Joule?

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.
