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 usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage.

Coal, Kentucky Geological Survey, University of Kentucky

Relative coal density is measured as specific gravity. Specific gravity is the ratio of the mass of an object (solid or liquid) to the mass of an equal volume of water at 4°C. For reference, the specific gravity of water is 1. Materials with specific gravities of less than 1 float in water. Specific gravities that are greater than 1 sink in water.
