A material has SG 1.40; what is its density in lb/ft^3?

Explanation:
Specific gravity compares a material’s density to that of water. In English units, the density of water is 62.4 lb/ft^3, and the material’s density is SG times that value. So the density = 1.40 × 62.4 = 87.36 lb/ft^3. Therefore, the material’s density is 87.36 lb/ft^3.
