Measurements done in QGIS on my project are done properly using whatever unit is set in:
Settings > Options > Map Tools > Preferred measurements units
but the scale bar decoration and scale bar in print composer are still degrees. My data is all NAD83. Previously answered questions state that it must be changed in project settings but I don't see that menu option in QGIS 1.80.
How can I change settings so that my scale bar is in units other than degrees?
EDIT 1: I don't have that option in the menu (are you using 1.80?), but I do have a button for 'CRS status' on the status bar. If I click that and change layer units to feet, which it indicates are only used when CRS transformation is disable, I get the following:
As you can see, the scale bar measurement is completely off. I can change the CRS to other systems than use feet other meters and it's more accurate. Are there metric and imperial version of NAD83, WGS84, etc?
If the measure tool can give figures in feet or meters when using a CRS with degree units, why can't the scale bar do the same?
