Megaelectronvolts to Joules Converter

Convert megaelectronvolts (MeV) to joules (watt-seconds) (J), 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 MeV = 1.602176634 × 10⁻¹³ J

Show the working
  1. 1 MeV = 1.602176634e-13 J
  2. 1 × 1.602176634e-13 = 1.602176634e-13 J

How to convert megaelectronvolts to joules

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

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

Worked example:

1 MeV = 1.602176634e-13 J
5 × 1.602176634e-13 = 8.01088317e-13 J
