mass ruumalaühiku kohta väljendatuna kilogrammides kuupmeetri kohta või grammides milliliitri kohta temperatuuril 15 0C ja rõhul 101,325 kPa, substance is its mass per unit volume, 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
