Joules to Megaelectronvolts Converter

Convert joules (watt-seconds) (J) 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.

Show the working
  1. 1 J = 6241509074460 MeV
  2. 1 × 6241509074460 = 6241509074460 MeV

How to convert joules to megaelectronvolts

1 J = 6,241,509,074,460 MeV, so multiply by 6,241,509,074,460 to go from joules (watt-seconds) to megaelectronvolts. Going the other way, 1 MeV = 1.602176634 × 10⁻¹³ J.

MeV = J × 6,241,509,074,460
J = MeV × 1.602176634

Worked example:

1 J = 6241509074460 MeV
5 × 6241509074460 = 31207545372300 MeV
