    <p>Dear Vineet Kumar,</p>
    <p>if you average the charge over a surface you'll get the charge
      per unit surface. Integrating this will give you the total charge
      per unit surface...</p>
    <p>I think the output of average.x is just this... Thus, you'll need
      to multiply by the xy-area of your unit cell...</p>
    <p>Regards</p>
