The density of a material is defined as its mass per unit volume. The symbol of density is ρ (the Greek letter rho).

The density of a material is defined as its mass per unit volume. The symbol of density is ρ (the Greek letter rho).

A very common instrument for the direct measurement of the density of a liquid is the hydrometer, which measures the volume displaced by an object of known mass. A common laboratory device for measuring fluid density is a pycnometer; a related device for measuring the absolute density of a solid is a gas pycnometer. Another instrument used to determine the density of a liquid or a gas is the digital density meter - based on the oscillating U-tube principle.

The density of a solid [[material]] can be ambiguous, depending on exactly how its volume is defined, and this may cause confusion in measurement. A common example is sand: if gently filled into a container, the density will be low; when the same sand is compacted into the same container, it will occupy less volume and consequently exhibit a greater density. This is because sand, like all powders and granular solids contains a lot of air [[space]] in between [[individual]] grains; this overall density is called the bulk density, which differs significantly from the density of an individual grain of sand.[http://en.wikipedia.org/wiki/Density]
