Question

Formula of the specific gravity?

Answer 1

Specific gravity of any substance is the ratio of that substance’s density to the density of water at 4 degrees Celsius. As the density of water at 4 degrees Celsius is 1,000 kg/m3, this ratio is very easy to calculate.

Specific Gravity = density of object
                              density of water

Answer 2

Specific Gravity = density of object
                              density of water
