How to Convert Megajoules to Electronvolts

To convert a measurement in megajoules to a measurement in electronvolts, multiply the energy by the following conversion ratio: 6.2415E+24 electronvolts/megajoule.

Since one megajoule is equal to 6.2415E+24 electronvolts, you can use this simple formula to convert:

electronvolts = megajoules × 6.2415E+24

The energy in electronvolts is equal to the energy in megajoules multiplied by 6.2415E+24.

For example, here's how to convert 5 megajoules to electronvolts using the formula above.
electronvolts = (5 MJ × 6.2415E+24) = 3.1208E+25 eV

How Many Electronvolts Are in a Megajoule?

There are 6.2415E+24 electronvolts in a megajoule, which is why we use this value in the formula above.

1 MJ = 6.2415E+24 eV

Megajoules and electronvolts 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.

What Is an Electronvolt?

An electronvolt is the amount of energy required to accelerate an electron through a difference in electric potential of one volt in vacuum. One electronvolt is equal to the charge of 1.602176634 × 10−19 C, and is equal to the energy of 1.602176634 × 10−19 Joules.[1]

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.
