How to Convert Kilojoules to Megajoules

To convert a kilojoule measurement to a megajoule measurement, multiply the energy by the conversion ratio. One kilojoule is equal to 0.001 megajoules, so use this simple formula to convert:

megajoules = kilojoules × 0.001

The energy in megajoules is equal to the kilojoules multiplied by 0.001.

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

5 kJ = (5 × 0.001) = 0.005 MJ

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

Kilojoules

One kilojoule is equal to 1,000 joules, which are 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 10³. Kilojoules can be abbreviated as kJ, for example 1 kilojoule can be written as 1 kJ.

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 10⁹. Megajoules can be abbreviated as MJ, for example 1 megajoule can be written as 1 MJ.
