If you're trying to align text and graphics you probably should be using the VDU 5 (write text at graphics cursor) mode, so you can use the same coordinate system for both.
Failing that you can find conversion functions between BBC BASIC graphics units and Windows pixel units here:
http://bb4w.wikispaces.com/Converting+graphics+coordinates
You may be able to use those to convert to text coordinates by dividing by the character width and height values (@vdu%!216 and @vdu%!220).
