For the answer to this dilemma, let us engage in a little
"dimensional analysis":

Yes, eV is a unit of energy.  Energy is also expressed
as mass*distance*distance/(time*time).  Divide that by
c^2 (c is in distance/time) and, lo and behold, you have
mass.  This is a common way of expressing mass in relativistic
physics, in accordance with Einstein's mass-energy relation:

                      m=E/c^2

where E is energy.
