Megajoules to Megaelectronvolts Converter

Convert megajoules (MJ) to megaelectronvolts (MeV), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of energy, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

1 MJ = 6.24150907446 × 10¹⁸ MeV

Show the working
  1. 1 MJ = 6.24150907446e18 MeV
  2. 1 × 6.24150907446e18 = 6.24150907446e18 MeV

How to convert megajoules to megaelectronvolts

1 MJ = 6.24150907446 × 10¹⁸ MeV, so multiply by 6.24150907446 to go from megajoules to megaelectronvolts. Going the other way, 1 MeV = 1.602176634 × 10⁻¹⁹ MJ.

MeV = MJ × 6.24150907446
MJ = MeV × 1.602176634

Worked example:

1 MJ = 6.24150907446e18 MeV
5 × 6.24150907446e18 = 3.12075453723e19 MeV
