Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3 Density Values of Different Construction Materials If two different materials are same in weight, but their density of both may be different. Lower dense material occupies more volume than higher dense material.
