Density is the mass per unit volume of a substance while specific gravity is an index that describes the ratio of the substance density to the density of water.

density if the ratio of an objects weight and volume. specific gravity is an object's density divided by the density of water. it is a dimensionless number (no units), and indicates an object's density respective to that of water.

Conceptually they are the same.
Specific gravity is just a relative measurement of density. It is convenient in some areas because it is easy to measure (at least approximately) using a hydrometer. It is inconvenient because it is strictly only properly defind at a set temperature, because liquids expand.
