Density expressed in g/mL and specific gravity have the same numerical value, but specific gravity is dimensionless as it is a ratio of densities. Density is expressed in mass/volume, while specific gravity is expressed as the ratio of the density of a substance to the density of a reference substance (usually water). Thus, they have different units.
