Have you tried the hpgl output to see if it is what you want?
The hpgl output will be in units of precisely 1/40 mm = 0.025 mm. (and approximately one thousandth of an inch), which I believe is standard practice for hpgl.
-------------
I made rectangle 1x1 mm - it is 50x50 hpgl units.
I export it to .plt file : IN;PU0,50;PD50,50;PD50,0;PD0,0;PD0,50;PD0,50;PU; - it is OK.
But when I open it or import it, I get rectangle 1,350x1,350 mm.
This new rectangle saved is : IN;PU0,63;PD63,63;PD63,0;PD0,0;PD0,63;PD0,63;PU; .
This new .plt file gives 1,675x1,675 mm when opened .....
