Specific gravity, also called relative density, is the ratio of the weight of a unit volume of some substance to the weight of an equal volume of purified water or some other standard substance at a stated temperature. Since the density of purified water is 1 g/cm 3, the difference between density and specific gravity is one of units

It's more theoretical and less empirical because you can't always be a hundred percent confident about how the gold will grind at a given size. It can tell you the size of the particles, but it won't necessarily tell you whether or not they're actually going to get released and separated at these various size ranges. Both are very useful.
