The About Time books provide as useful a set of definitions as I've seen.
"Sf/fantasy" is stories about things that are, as far as we know right now (or at the point in time when the story is set), impossible in the real world. (This would include history having gone a different way from the way we know it went.)
Within that overall category, sf is broadly about humanity's relationship with its tools, and fantasy about humanity's relationship with its symbols.
