The best solution is to set the internal basic unit to nm (it seems to 
be the consensus), so that the number 1 == 1nm, and make a typedef in
some header file. Then Armin can have his long long, I can have my
doubles, some can have their int64_t, and most can have their simple
int. And we can all test and make sure that pcb is typeagnostic 
regarding that typedef.

Then, whoever wants forestsize_pcbs/kitchens/antennas/etc.,
simply choose their right type (and no scaling factor would be
needed).
