Term: mass density
Synonym1: density
[Preferred]
Synonym2: volumic mass
[Preferred]
Synonym3:
Symbol: ρ
Definition: at a given point within a three-dimensional domain of quasi-infinitesimal volume dV, scalar quantity equal to the mass dm within the domain divided by the volume dV, thus ρ = dm/dV

NOTE 1 Mass density is an intensive quantity describing a local property of a substance.

NOTE 2 The concept of mass density may also be applied to the mass m in a domain D with volume V, leading to the average density ρ av = m V = 1 V D ρdV MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiabeg8aYnaaBaaale aajugWaiaabggacaqG2baaleqaaOGaeyypa0ZaaSaaaeaacaWGTbaa baGaamOvaaaacqGH9aqpdaWcaaqaaKqzaeGaaGymaaGcbaGaamOvaa aadaWdrbqaaiabeg8aYLqzaeGaaiizaOGaamOvaaWcbaqcLbmacaqG ebaaleqaniabgUIiYdaaaa@4C27@ .

NOTE 3 The coherent SI unit of mass density is kilogram per cubic metre, kg/m3. Other units are tonne per cubic metre, t/m3 (1 t/m3 = 1 000 kg/m3 = 1 g/cm3), and kilogram per litre, kg/l (1 kg/l = 1 000 kg/m3).
