Re: gEDA-user: pcb, how to remove mm garbage (very short lines)?

The Pads ASCII format uses a base unit of 0.00000002624671916 inches
which is 1.0333354 nM

Converting it to metric causes an error of about 0.5 nM

The PCB base unit is 0.00001 inches 

Converting it to metric causes an error of 19.7 nM

All I can figure out about why pads uses that weird number is that
multiplying it by 38100 converts the base unit to mills

Multiplying it by 9678 converts the base to 10 microns with an error
of .6 nM


So making the base smaller will reduce error (no surprise) the question
is what is a tolerable error?
