Unit conversion problem

I have a problem with some files that were made in Pro/E and converted to Solidworks (not by me).  Problem is that the units have somehow been converted incorrectly.  For instance, a part that should be 495mm in length is actually 495inches in length.  How do I convert these files to mm, while keeping the same dimensional values?

Thinking back to my Pro/E days, there was a unit conversion function that allowed to to change the unit system while leaving the numbers the same. Is there a similar function in Solidworks?... or a workaround?
