How to Convert Electronvolts to Megajoules

To convert a electronvolt measurement to a megajoule measurement, multiply the energy by the conversion ratio. One electronvolt is equal to 1.6022E-25 megajoules, so use this simple formula to convert:

megajoules = electronvolts × 1.6022E-25

The energy in megajoules is equal to the electronvolts multiplied by 1.6022E-25.

For example, here's how to convert 5 electronvolts to megajoules using the formula above.
5 eV = (5 × 1.6022E-25) = 8.0109E-25 MJ

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


The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

Electronvolts can be abbreviated as eV, for example 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.


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.
