Field Calculator in QGIS

In QGIS, if you want to calculate the real geometries (such as area, parameter, length etc.) of polygon/point based on the current coordinate system, we need using the field calculator.  If we use this calculator, we able to show the geometries in the features table. I list a few field calculators that may interest the QGIS user as follows:


latitude and longitude

$x or $y as a variable to get the x and y
