Feb 17, 2010  If we assume the volume of the ballast doesn't contribute much to the total volume of the diver/ballast (we could calculate the volume of the ballast to see that this will likely be the case), the total weight of the diver/ballast will be proportional to the density of the fluid they're submerged in. (W + w)/(ρw) = (W + 1.5w)/(ρs)

Track ballast - Wikipedia

The depth of ballast also tends to vary with the density of traffic, as faster and heavier traffic requires greater stability. The quantity of ballast also tends to increase over the years as more and more ballast is piled on. Some figures from an 1897 report are: first class line – 60 lb/yd (29.8 kg/m) rail – 1,700 cu yd/mi (810 m

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
