Specific Gravity Calculator
If you want to determine whether an object will sink or float, you can use our specific gravity calculator.
In physics, specific gravity, also known as relative gravity, is defined as the relationship between the densities of a substance and water at a particular temperature. Or in other words, the ratio between the substance's density and water density is called specific gravity. At the same time, the specific gravity has no unit because the unit of both substance density and water density are canceled out in the formula. That is why it is a dimensionless quantity.

Formula of Specific Gravity Calculator
To instantly find out the gravitational potential energy absorbed by an object, you can jump to our calculator. Or to find it manually, you can use the formula listed below:
\[SG\; = \;\frac{{\rho \;substance}}{{\rho \;{H_2}O}}\]
Where,
SG = Specific Gravity
ρ substance = density of a substance
ρ H2O = density of water
Example
For a more precise understanding of how to find the specific gravity, let us have an example below:
Suppose the density of gasoline is 721 kg/m3. Then find out the specific gravity of gasoline.
Given data
The density of gasoline = 721 kg/m3
The density of water = 1000 kg/m3
To Find
The specific gravity of water = ?
Solution
To find the specific gravity of water, you can use the formula listed below:
\[SG\; = \;\frac{{\rho \;substance}}{{\rho \;{H_2}O}}\]
Putting values in the formula:
\[SG\; = \;\frac{{\;721}}{{ \;{1000}}} = 0.721\]
Note:
To calculate acceleration due to gravity, you can use our Acceleration Due To Gravity Calculator.
