Specific Gravity Formula

Specific Gravity gives information about the weight and density of the object. It can be calculated by comparing the weight, mass and density of the given object with water of the same amount at 40C.

Specific Gravity Formula is expressed as

Specific Gravity Formula -1

or

Specific Gravity Formula -2

or

Specific Gravity Formula -3

Specific gravity is a unitless measurement. The density of water is 1000 Kg/m3
