I think we already have nice units for you. You can use points and
picas. "Point" allows to specify one decimal place and this brings you
down to an accuracy of 1/720 inch. Considering your animosity against
decimal units lets me think that "1/720" is much better for you than
"1/100" or "1/1000". ;-)

Well, every change creates effort. And not only in development but also
in QA, documentation etc.
