[Pw_forum] Unit of pp.x charge

[WF]

This is stated in pw.x, cp.x and neb.x help documetations, however pp.x
manual doesn't say that so I am not sure whether it is still applicable. And
due to I made an error in summation of the charge density and volume, I
thought it is not (Bohr)-3. 
Thanks for your help very much.

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}
