@Mr.Wizard Well honestly, what do you expect from E^Quantity[0, "Feet"]? Exponents are dimensionless quantities, and raising something to a number of feet (even if it's zero) doesn't really make sense, so I wouldn't expect Mathematica to do anything sensible (in fact, an error would be nice). That being said, in the equation in the example, the remaining variables are still able to cancel out the units, so I don't really know what to expect in that case.

I marked this as a bug. A reduced example: x*E^Quantity[0, "Feet"] // FullSimplify

The bug seems to be in FullSimplify (which always tries harder). Compare A[Quantity[0, "Seconds"]]; Simplify@A[Quantity[0, "Seconds"]]; FullSimplify@A[Quantity[0, "Seconds"]] screen shot: !Mathematica graphics
