as stated in the top line of the documentation  of input:

  All quantities whose dimensions are not explicitly specified
  are in RYDBERG ATOMIC UNITS

What may not be completely clear is that the charge is "number"
charge, i.e. not multiplied by e; potentials are energies, i.e.
multiplied by e. So, charge is in (Bohr radii)^{-3}
