Density - Wikipedia Density (volumetric mass density or specific mass) is the ratio of a substance's mass to its volume The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D (or d) can also be used: [1] =, where ρ is the density, m is the mass, and V is the volume In some cases (for instance, in the United States oil and gas industry), density is loosely
Density | Definition, Symbol, Units, Formula, Facts | Britannica density, mass of a unit volume of a material substance The formula for density is d = M V, where d is density, M is mass, and V is volume Density is commonly expressed in units of grams per cubic centimetre For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5 51 grams per cubic centimetre Density can also be expressed as kilograms per cubic metre (in
