Evaluation, data handling:

The density (r) of a test item is the quotient of the mass (m) and the volume (V) of that substance at a specific temperature.

SI unit is in [kg/m³]. 1 [g/cm³, g/mL] corresponds to 1000 [kg/m³]

The relative density of solids or liquids is the ratio between the mass of a volume of substance to be examined, determined at 20 °C and the mass of the same volume of water, determined at 4 °C. The relative density has no dimension.

The density (r) of water at 4 °C is 1 g/mL. If the test is performed at 20 °C ± 1 °C, the relative density () is given by the value of the density (r).
