[Qgis-user] How Do I Set Field Calculator Units For Area

[Alister Hood]

Hi Giovanni,
Either you are mistaken, or there is a bug.  I have OTFR enabled, and the field calculator returns the same area when I set the project CRS to EPSG:32074 (which uses feet), as it does when I set the project CRS to any normal CRS which uses metres.
