If the software has hardware attached that could potentially have a 
higher or lower precision in terms of the specific metric it/ they 
measure(s), you have a place to configure it outside of the code based 
on the attached hardware. This makes the software more flexible; for 
users as well as developers. Also, seeing it named in the code makes it 
clear which constant will affect which display.

Perhaps that is irrelevant. Hard to say =]
