Assign coordinates to grid-cell in QGIS

Question

I've created a grid using make grid in QGIS. The type of grid is rectangular (polygon) and it's 0,1 x 0,1 decimal degrees. I now want to assign an X and Y coordinate to the centre of each grid. Would anyone know how to do this?

Answer 1

You can open the field calculator and add a new field centroid_x, type decimal, computed as x(centroid($geometry)) (the X coordinate, of the centroid of the current (=each) geometry.)

Add a second field centroid_Y computed as y(centroid($geometry))
