To convert a measurement in kilojoules to a measurement in megajoules, divide 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:

megajoules = kilojoules ÷ 1,000

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

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

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

What is a Kilojoule?

One kilojoule is equal to 1,000 joules, which is the energy equal to the force on an object of one newton at a distance of one meter.

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for thousands, or 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.

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.
