Structural Damage due to High Density Cargoes High density cargoes have a greater weight than their volume may imply. Lighter cargoes occupy more space. For example, the stowage factor for corn is 1.42 m3/tonne while for iron ore, the stowage factor can be as small as 0.24 m3/tonne. Tanktop strength is provided in the ship's stability booklet .

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft.
