Using Bitstream Versa Sans Mono font and setting it to 8pt I typed the 
following text:  lygAÀ

Using Gimp I took a screenshot and measure the top of 'À' to the bottom 
of 'g' and it was 12 pixels high. The letter 'B' is 8 pixels high. I'm 
running my X11 and a forced 96 dpi. Using Ubuntu 8.04.2 with Gnome desktop.

So again, using your formula, I have no clue why fonts vary in size 
depending on different platforms yet using the same dpi setting. It 
seems everybody has there own formula for converting points to pixels.
