A Newton*Meter (N·m) is a Joule (J) and a Joule is the derived unit of energy in SI units. N=(kg*m/s^2) so a N·m=(kg*m^2/s^2)=J.

An electron volt is also a quantity of energy equal to approximately 1.602×10−19 J.

Correspondingly, one joule equals 6.24150974×1018 eV.

By definition, it is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electric potential difference of one volt. Thus it is 1 volt (1 joule per coulomb) multiplied by the electron charge (1 e, or 1.60217653(14)×10−19 C).

Therefore, one electron volt is equal to 1.60217653(14)×10−19 J.

The electron volt is not an SI unit and its value is derived from knowing the charge of the electron.

To change Js to eV divide by the charge of an electron 1.602x10-19 C.

To change eVs to Js multiply by the charge of an electron 1.602x10-19 C.
