I have a shapefile which the .prj file says it is


QGIS's on the fly reprojecting is not working. It has worked well enough for me so far but I can't seem to figure out how to change the UTM to feet from meters.

UTM is always in metres, being internationally standardized. The proj string for UTM 15N is:

+proj=utm +zone=15 +datum=WGS84 +units=m +no_defs

So if your data is in feet, create a custom CRS with this string:

+proj=utm +zone=15 +datum=WGS84 +units=us-ft +no_defs

or look for the NAD83 projections of the US state your data is about.

EDIT: To add a custom CRS:

  • Settings -> Custom CRS

  • Click on the yellow star to create a new CRS

  • Enter a name, like UTM15 ft

  • paste the proj string in the second line

  • Click on the save button
