Description
A measurement of the weight (or mass) per volume of a material. Density is usually expressed as grams per cubic centimeter (milliliter) for solids and liquids. The density of gases is expressed as grams per liter. A related term, specific gravity, is the density of a material divided by the density of water, which is usually 1.0. In practical term, a high density material is usually heavy and impenetrable, such as lead. A porous material, such as a foam or paper will have a low density. The term density is also used to refer to the optical opacity, or blackness, of a material.
