density, volumetric mass density, volumic mass, specific mass, weight density, unit weight, volumetric weight
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
