Material Density

Specific Gravity - Definition

Specific gravity is nothing but relative density which measures the density of the object with respect to pure water density. Here, the reference object used is water which has a density of water is 1000 Kg/m3.

Specific Gravity = density of substance/density of water

How to Calculate Specific Gravity?

We are providing you with a specific procedure to calculate specific gravity using a specific gravity calculator.

  • Enter the values for density of substance and density of water.
  • Then click on calculate.
  • You will get value for specific gravity.

Specific Gravity Formula

SG = ρsubstancewater,


SG is the Specific Gravity

ρsubstance is the density of the object

ρwater is the density of water

Example to Calculate Specific Gravity?

Question : Find the Specific Gravity for 8kg/m3?


Given Parameters,

Density of object = 8kg/m3

We know that, Density of water = 997 kg/m3.


SG = ρsubstancewater = 8/1000 = 0.8

Value of SG = 0.8 kg/m3.

Not only this we have a calculator for every formula in physics. Click on this link to know more
