Well Galactus power varies... In a relative weak state he would equal Pre-crisis Darkseid.
Than we have the ordenery state, which is about a average Celestial.
Than the well feeded sate he could probobly take on some of the more powerful abstract's.
In full power he would be a unity with the universe, in other words the same as Eternity. And Eternity can destroy a universe with all dimentions in it (In comics it works like that, all dimentions in a universe, but in real world each universe is a dimention.)
