How do I calculate the latitude and longitude of points using QGIS?

I'm trying to figure out how to calculate the lat/long of points using the QGIS field calculator. Is there an easy way to do this? I saw a previous related question, but it deals with a more advanced approach.

In ArcGIS this is similar to the Calculate Geometry function; I just can't find where do this in QGIS.

Answer

Sure can. First, save the layer as WGS84 and import it again. Then in the field calculator you can use $x or $y as a variable to get the x and y.

NOTE: This was added in 1.7.
