I have some data in Michigan State Plane NAD83 in International feet. Does anyone know if this is accounted for when adding this data set to a map in Michigan State Plane 83 in USfeet?
Yes, when we unproject/project data, we look at the actual unit that are listed in the coordinate system definition. The false easting/false northing values must be in the same unit so if you compare the int'l ft and US survey ft definitions, you should see slightly different numbers.
If they do have a different code EPSG code, I presume they would project on the fly

That is my quandary. The FIPS code is the same, but the units are different. Does arcgis recognize feet_int versus USfeet and account for it?
The data that I have produced and the data that someone else has produced do not align, so I am fishing for the reason.

Isn't the FIPS code a county code (Canadian here, so bear with me).
I was more interested in what the actual coordinate system was for each file. If they were defined the same but differ in placement, then the units and/or datum (nad whatever) would account for the shift).

Thank you Melita, this answers my question.
