Numbers within units (50g)

I guess I'm asking: "Since you can put a number in the conversion factor (as you've demonstrated above), is it possible to "call" or "peek" a value from somewhere else and apply it as part of the conversion?"

After a few days I found myself needing something similar, so your idea wasn't so crazy after all.
I'm not really looking at a variable conversion rate, but I need the conversion rate to have variable precision, therefore it's a different number depending on the system precision (practically, it's the same problem for a different purpose).
Think for instance the conversion from degrees to radians. The factor pi/180 would need to be recomputed at the current system precision to produce an accurate conversion, so I do need a way to recall a constant 'pi/180' from some external source, rather than have a number pre-computed as part of the unit definition.
I'm writing this because my own post made it seem like a not-so-good idea (at the time). Now it hit me, and I need to implement it somehow (still trying to figure out that part).
