Its symbol is ρ (the lower case greek letter rho).

Units of density. The dimension of density is the measurement of how dense the substance is composed of. Water is considered a universal matter, and the density of water at 25 °c is 1000 kg/m 3 or 1 g/cm 3. Units of density are g/cm 3.

Density, or the volumetric mass density, of a substance is its mass per unit volume. It is a measurement of the amount of a substance contained in a certain volume. Density is mass per volume, weight per volume, or specific gravity, which is the density of a material per the density.

For example, the density of gold is 19.32 g/cm 3, and so the specific gravity is 19.32. The mass of any substance per unit volume of a material is defined as absolute density. The density of an object.

The density of water is equal to \(1\) gram per cubic centimeter; The kilogram per cubic meter unit of measurement is also used to express density. Density is a way of comparing how heavy different materials are.

The si units of density are kg/m 3. Ounces and pounds are in the avoirdupois system, the standard everyday. The formula for calculating density is p = m/v, where p is the density, m is the mass and v is the volume.

Convert among mass density values along with mass concentration values (mass divided by volume). The unit of absolute density is g/cm 3. Put another way, density is the ratio between mass and volume or mass per unit volume.
