• Density and density measurement :: Anton Paar Wiki

    The values of apparent density and true density are different, even if their units are identical. The true density of air at 20 C as measured in a density meter is 0.0012 g/cm whereas the apparent density of air at 20 C is 0.0000 g/cm – air on a balance does not give a reading.
