Specific gravity: Calculating Specific Gravity Specific gravity

Calculating Specific Gravity Specific gravity is determined by dividing the density of a material by the density of water at 4 degrees Celsius. For the calculation, the density of the material and that of the water must be expressed in the same units. Specific gravity, also known as relative density, measures the density of a substance compared to the density of water. Specific gravity is related to density, as both are physical properties used to determine how "dense" a particular material is. This material can be a gas, liquid, or solid. Relative gravity or Specific gravity can be defined as the density ratio of a substance to that of water at a specific temperature . Therefore, Specific gravity tells us if an object will sink or float. Specific gravity , also known as relative density, refers to the ratio of density of any substance to the density of the reference substance.
