That you abandon such notions of encoding.

You are assuming that the representation of "denominator" permits negative 
values. It might not. Further, attempting to encode different meanings into a 
single value in this manner generally leads to code that is less efficient 
and often becomes the source of coding errors.

Where I need to store these conversion factors, I would store them in (some 
equivalent of) rational numbers where these have both a numerator and a 
denominator, even though in all cases that I have observed one of those will 
be unity.
