What does 1 electron-volt represent?

It is the energy an electron gains when accelerated through an electric potential difference of one volt, equal to exactly 1.602176634×10⁻¹⁹ joule.

How is 1 megaelectron-volt related to electron-volts?

1 MeV equals one million electron-volts; specifically, 1 MeV = 10^6 eV.

When should I use MeV instead of eV?

MeV is preferred for representing very high energy values found in nuclear and particle physics to provide clearer and more manageable numbers.
