Question

The numerical value of ionization energy in eV equals the ionization potential in volts. Does the equality hold if these quantities are measured in some other units?

Answer 1

The equality does not apply if those quantities are expressed in some other units.

Explanation:

The electron volt represents the net energy that is provided to an electron to pass it through the 1 volt Possible electrical difference.

1 electron volt Is equivalent to $1.6 \times 10 ^{-19} J$

The ionization energy numerical value in is equivalent to the volt ionization potential. If those quantities are expressed in some other units, the similarity does not apply.
