    The ratio of the density of a substance to the density of a reference substance, usually water for liquids and solids, or air for gases.

    zh相对密度

    • The relative density of gold is 19.3, meaning it is 19.3 times denser than water.
    • To calculate relative density, divide the density of the substance by the density of water.
    • Relative density is a dimensionless quantity, as it is a ratio.
