Thanks all for the comments & insights!  I hope John got the info he needed
from this thread, but even if he didn't I certainly found it informative!

This was something I had recently been running up against since my
"architecture" IRTC entry. That one pretty much demanded a standardized
method of scaling, so I started using feet since most building specs (at
least here in the US) are in feet.

Once I started using that though, I found I had problems with earlier models
where I had hard coded numbers or used arbitrary unit sizes. Some were so
bad it was easier to build a new model than to convert the old one!

So now I have my unit standard, and it sounds like enough people are using a
system similar enough that conversion shouldn't be a major issue. (And I
should have some good objects to share in my surreal IRTC entry, as long as
I get it done in time...)

Thanks again!

RG
