I am and my fellow colleague both of us using same version QGIS i.e., QGIS 2.8.3 and same CRS - NAD27 EPSG:4267, the problem is when we measure certain length of the feature(Using measure line option in QGIS), in her QGIS it displays say for ex: 300m and in mine the same length will be displayed as 450m. I crosschecked the results with some manual measurement the one displayed as 300m is correct. Also, we figured that this discrepancy is only for x- co-ordinate( Horizontally). Why such discrepancy even though we are using same version and same CRS. What settings can help us to get same and correct resutls?
