Description
When changing a project's Map Units from Meters to Feet (or vice versa), the value displayed in the scalebar, and the values given by the distance (ruler) tool are wildly wrong.
- Create new project with a single layer. Set correct project Projection and Map Units (eg. UTM NAD83).
- Scale bar read eg. 50 km
- Measure distance between two points, eg "Segments (in meters)" 88,711.91, total 88.71 km
- Change Map Units in project Properties to Feet. Hit refresh.
- Scalebar is same size, now says 9.4697 miles (WRONG: should be ~31 miles)
- Measure same distance, eg "Segments (in feet)" 89,177.93, total 16.89 mile (WRONG: the displayed number of segments are really meters, the "total" count converts feet to miles, should be converting meters to miles or should be counting feet instead of meters)
Note:

for help on using tickets.
This is the intended behaviour. It is not meant to perform conversion, but to specify that one unit of the map represent a foot, meter or degree. Mostly used when no projection is appropriate (such as drawing a plan of your house).
