· The density of any material is derived by multiplying the specific gravity of that material by the density of pure water. For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal. Conversely, to convert from density to specific gravity, divide the density of a material or mud by the density of pure water.
