Hi I also have a problem with the measureing tool on Windows. I don't know if I use it wrongly, but I experienced the same problem on both 0.11.0 and 1.0.0. I changed the Settings -> Project Properties -> Map Units to Meters (from degrees) in the hope that the measuring tool would display the measured distance in meters. Although the measurement popup show that the units are meters, that actual displayed distance is the same as was shown for the degrees. The some problem persists if I you change the units to feet. If I remember correctly, it work fine on my Mac OS X Tiger at home. Regard Louis Becker

What lhbecker describes is the intended behaviour. The settings describes the size of one map unit i.e. the distance from coordinate (0,0) to (0,1).

I still need more info about the problem the original submitter has.

My problem would then be that the measuring tool shows the unit "m", when in fact the the measurements are being done in degrees. The result does not match the units. One should then not be allowed to change the measurement units once you've chosen a specific projection with corresponding units.

There is now a warning that measuring in latlong CRS gives not-so-reasonable results. This is inherent to the projection system, not a bug of QGIS INHO
