• Specific Gravity Of Metals Table

    2013 10 3 For example beryllium has a specific gravity sg of 1 84 1840 kg/m³ As specific gravity is just a comparison it can be applied across any units The density of pure water is also 62 4 lbs/ft³ pounds per cubic foot and if we know that a sample of aluminum has a sg of 2 5 then we can calculate that its density is 2 5 x 62 4 = 156 lbs/ft³
