- Specific gravity is also termed as relative density.
- The relative density/specific gravity of a substance is defined as the ratio of the density, mass or weight of the substance to the density, mass or weight of water at 4°C
- Specific gravity is the ratio of the specific weight of the liquid to the specific weight of a standard fluid.
- In case of liquids standard fluid is taken as water with specific gravity 1.
\({\rm{\gamma }} = \frac{{{\rm{Density\;of\;Substance}}}}{{{\rm{Density\;of\;same\;volume\;of\;water}}}} = \frac{{\rm{\rho }}}{{{{\rm{\rho }}_{\rm{w}}}}}\)
The specific gravity of mercury is given as 13.6, which means that it is 13.6 times denser than water.
The density of water at 4°C is 1000 kg/m3. Therefore, the density of mercury at 4°C can be calculated as:
density of mercury = specific gravity x density of water at 4°C
density of mercury = 13.6 x 1000 kg/m3
density of mercury = 13600 kg/m3 = 13.6 g/cc
