Specific gravity is a unitless measure, because it is derived from the density of the mineral divided by the density of water and thus all units cancel. However, since water's density equals 1 gram per cubic centimeter (at specific conditions), then a mineral's specific gravity would also correspond to a mineral's density as expressed in grams per cubic centimeter.

Fly ash or flue ash, coal ash, and also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coalfired boilers together with the flue that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is ...
Coal Hardness And Specific Gravity Wikipedia. Properties of Marble Physical Thermal. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 13 are soft rocks from 36 are medium hardness rocks and 610 are hard rocks.
Specific gravity Wikipedia. Specific gravity varies with temperature and pressure reference and sample must be compared at the same temperature and pressure or be corrected to a standard reference temperature and pressure. Substances with a specific gravity of 1 are neutrally buoyant in water. Get Price; Coal assay Wikipedia. Relative density.
· Since specific gravity is relative to the weight of an object in air and its weight in water, it is a ratio and isn't expressed in units (such as kg/m³). For instance, the SG of Diamond = (whereas the density of Diamond = g/cm³). In gemology, specific gravity is, usually, determined through an apparatus based on Archimedes' Principle.
