The SI derived unit for **energy** is the joule.

1 MeV is equal to 1.6021773E-13 joule.

Note that rounding errors may occur, so always check the results.

You can do the reverse unit conversion from J to MeV, or enter any two units below:

The SI prefix "mega" represents a factor of
10^{6}, or in exponential notation, 1E6.

So 1 megaelectronvolt = 10^{6} .

The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).
