How to Calculate Specific Gravity

Specific Gravity is the ratio of the density of a soil to the density of water. Where: SG = Specific Gravity (dimensionless) ρs = bulk density of soil (kg/m3 or lb/ft3) ρw = bulk density of water (kg/m3 or lb/ft3) = 1000 kg/m3 (62.4 lb/ft3) Specific Gravity of Various Substances Substance Specific Gravity Water 1.0 […]
