How do I fix this issue?

Whenever I open a parasolid or step/iges, I want the units to come in feet and inch 1/16 fractions, how do I do it.  I have created our model formats to do so, we have mm, inch fractional and feet and inch 1/16 fractions.  I am guessing there is another default file somewhere solidworks is using to open the imported geometry.
