How to Convert Megajoules to Kilojoules

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

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

kilojoules = megajoules × 1,000

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

For example, here's how to convert 5 megajoules to kilojoules using the formula above.
kilojoules = (5 MJ × 1,000) = 5,000 kJ

How Many Kilojoules Are in a Megajoule?

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

1 MJ = 1,000 kJ

Megajoules and kilojoules 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 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.
