Dear VASP-support,
I would like to know what the unit of the total charge (printed in OUTCAR) is.
Thank you.
With kind regards, Siaufung Dang

This file contains the lattice vectors, atomic coordinates, the total charge density multiplied by the volume $ \rho(r)* V_{\rm cell}$ on the fine FFT-grid (NG(X,Y,Z)F), and the PAW one-center occupancies.
see
http://cms.mpi.univie.ac.at/vasp/vasp/CHGCAR_file.html for more detail.
if you sum all the numbers in CHGCAR and divide it by the number of grids then you will get the number of electrons
