Specific gravity is a comparison of the density of an object with the density of? Specific gravity is the density of an object or liquid in comparison to the density of water at an exact temperature and an exact pressure. Changes in temperature and pressure effect the density of objects and liquids and therefore effect the specific gravity of objects and liquids. Specific gravity is a measure of density relative to the density of a reference substance. The reference material could be anything but the most common reference is pure water . If a material has a specific gravity less than 1 it will float on water. Specific gravity is often abbreviated as sp gr . Specific gravity is an expression of density in relation to the density of a standard or reference (usually water). Also density is expressed in units ( weight relative to size ) while specific gravity is a pure number or dimensionless. They are not however identical measures. Specific gravity is the density of an object or liquid in comparison to the density of water at an exact temperature and an exact pressure. Changes in temperature and pressure effect the density of objects and liquids and therefore effect the specific ...
