Example: the .stp file is exported in meters, but once I import the file via Merge the unit gets changed to millimeters (or in other words the geometry gets scaled by a factor 1000). So once I reimport the mesh it is also scaled up by a factor 1000.

We use OpenCASADE to import .stp files; if there's a 1000x scaling, probably the files have some mm units referenced in them? (Gmsh does not have any units.)
