What Is the Bulk Density of Coal? - Reference.com

It is a mature coal and is very hard and shiny. Bituminous coal has a bulk density of 42 to 57 pounds per cubic feet, or 673 to 913 kilograms per cubic meter. It ignites easily and burns long with a relatively long flame. Lignite coal has a bulk density of 40 to 54 pounds per cubic feet, or 641 to 865 kilograms per cubic meter.

Relative density - Wikipedia

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). ). The term "relative density" is often preferred in ...

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.
