The ionization energy measures the amount of energy it takes to remove an electron completely from a neutral, ground state atom in the gas phase. The units are always units of energy (check out a chem textbook or Wikipedia).

The ionization energy of an atom measures how strongly an atom holds its electrons
The ionization energy is the minimum energy required to remove an electron from the ground state of the isolated gaseous atom

Ionization energy measures the amount of energy need to remove an electron from an atom.
It is measured in Joules.

ionization is enthalpy change when gaseous atom gives out electron
A(g)--->A+(g)+e- dH=ionization enthalpy
units=j/mol or kj/mol
