If the purpose of the calculation is to obtain a general estimate for the tonnage of coal on a property or a regional average resource estimate, site-specific information (the details of coal composition) are not needed and an average coal density is commonly used for the calculation. Relative coal density is measured as specific gravity.

Basic calculation. Relative density(RD) or specific gravity (SG) is a dimensionless quantity, as it is the ratio of either densities or weights = where R+D is relative density, ρ substance is the density of the substance being measured, and ρ reference is the density of the reference. (By convention ρ, the Greek letter rho, denotes density.). The reference material can be indicated using

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, air at room temperature (20 °C or 68 °F) is the reference. The term "relative density" is often preferred in

Density, Specific Gravity Definition: Density and specific gravity have very similar, but not quite identical definitions. Density is the mass of material per unit volume. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 o C. Because specific gravity is a ratio, it is a unitless quantity.
