Hi, I am fighting this again. Looking at the $area function description it says:
"Returns the area of the current feature. The area calculated by this function respects both the current project's ellipsoid setting and area unit settings. For example, if an ellipsoid has been set for the project then the calculated area will be ellipsoidal, and if no ellipsoid is set then the calculated area will be planimetric." But whatever I do in the project properties, $area always returns me the results in the same unit, the layer's units. But if I check the measurement tools and the derived area in the feature identify results, the values are converted to the unit I have chosen. The project and the layer are at the same CRS which is in feet. What is wrong? - the $area function? - It's description? - Or me? thanks!
