One way to accomplish this is with the MapBasic Window.
First, explicitly set the coordinate system to what you want. For example:
Set CoordSys Earth Projection 13, 62, "m", 0
Then update the column with coordinates from that system:
Update Test_Table Set x_column = CentroidX(obj)
Update Test_Table Set y_column = CentroidY(obj)
You can easily get the coordsys clause to use by opening the MapBasic
window
and setting the map window to the coordsys that you want.
