The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:

5.1 Relative density (specific gravity) is the ratio of mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles – also referred to as the absolute volume of the aggregate. It is also expressed as the ratio of the density of the aggregate particles to the density of water. Distinction is made between the density of aggregate particles and the bulk ...

Assumed values: sand porosity = 0.3, specific gravity of sand= 2.65, breaking index = 0.78. To change the output values of Q and G for a different value of porosity (p), multiply the output values by (1-0.3)/(1-p). For a different specific gravity (s), multiply the output by (2.65 - 1)/(s-1). The formula used to calculate Q is:
