Density (disambiguation)

Density and dense usually refer to a measure of how much of some entity is "in" a fixed amount of other space. Types of density include: In physics:Density, mass per volumeArea density, mass over a (two-dimensional) areaLinear density, mass over a (one-dimensional) linePlanck density, Planck mass per Planck lengthSpecific gravity, a dimensionless ratio based on the density of a substance to the density of waterRelative density, a measure of density in comparison to the density of something elseVapour density, a relative density used for gasesCurrent density, the ratio of electric current to areaCharge density, the electric charge per volumeEnergy density, potential energy per unit volume or mass, depending on contextForce density, force per unit volumeInformation density, the amount of information compared to many unitsOptical density, the absorbance of an element
