How to calculate area using field calculator in QGIS?

If I were you, I would start a fresh map in QGIS, load the layer you want to perform calculations on, then process your Field Calculator expressions while both the layer and the map are in the same projection–that of your native data. It would be wise to double check that the QGIS map takes the projection of your data before you run the numbers.

Is the QGIS layer calculator respecting the projection?

It would be wise to double check that the QGIS map takes the projection of your data before you run the numbers. At least this way, you know QGIS’s layer calculator is respecting the intended projection. If you still get an unexpected result, my guess is your data may not be in the datum/coordinate system you actually think it’s in.

Is it possible to filter records out of attribute table?

It is also possible to filter features using the Filtering and selecting features using forms. Filtering records out of the attribute table does not filter features out of the layer; they are simply momentaneously hidden from the table and can be accessed from the map canvas or by removing the filter.

Is the QGIS program a 2D GIS program?
