density of materials Bulk Materials.

The mass of over 300 different 'dry' materials are listed below. Liquids, metals and woods are on other pages and a site search facility is on the home page. The data is useful for the design and selection of bulk materials handling plant, bulk transport and packaging, individual samples will differ. Moisture content will have a marked influence.

As 1000kg of pure water = 1 cubic metre, those materials under 1000kg/cu.m will float; more dense will sink ie. those materials with a specific gravity more than 1.
Pure water was chosen as the 'base line' for specific gravity and given the value of 1. The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic metre) (see table below)
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
