Try this post as a very similar question was asked:

Seems back then it wasn't possible to use field calculator in this way for polygons, but Underdark published a work round.

I'm interested in seeing if there's a 'real' answer (without a workaround) to this question now, as I see there's a 'centroid' function in the field calculator which I don't think was there before. However, I played with it, and am also unclear on the syntax. Perhaps there is a better answer to this question after all, using 1.9.0 Master.) – Darren Cope Aug 30 '13 at 12:17
