eV to joule Conversion

Here an examples how to convert the unit of energy in eV to joule. Some questions do need this conversion to get the result.

5 MeV = .... joule

You knew already that M mean Mega = 10⁶ , and eV is electronvolt.

Take an attention that
1 eV = 1,6 x 10⁻¹⁹ joule

So then we have

5 MeV = 5 x 10⁶ x 1,6 x 10⁻¹⁹ joule
5 MeV = 8 x 10⁻¹³ joule
