Specific Gravity Calculator


About Specific Gravity Calculator (Formula)

A Specific Gravity Calculator is a tool used to calculate the specific gravity of a substance, which is a measure of its density compared to the density of water. This calculation is important in various scientific and industrial applications, including chemistry, physics, and engineering. The formula used to calculate specific gravity involves dividing the density of the substance by the density of water.

The formula for calculating specific gravity (SG) is:

Specific Gravity (SG) = Density of Substance / Density of Water


  • Specific Gravity (SG) is a dimensionless value representing the ratio of the density of the substance to the density of water.
  • Density of Substance is the density of the material being measured, typically measured in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).
  • Density of Water is the density of water, typically measured in the same units as the density of the substance.

Using the Specific Gravity Calculator involves these steps:

  1. Input: Enter the values of the density of the substance and the density of water into the calculator. Ensure that the units for density are consistent.
  2. Calculation: The calculator divides the density of the substance by the density of water to calculate the specific gravity.
  3. Output: The calculator displays the calculated specific gravity value.

This tool is particularly useful for scientists, researchers, and professionals working with various materials and substances. It allows them to determine the relative density of a substance compared to water and understand its buoyancy and behavior in different environments.

For example, if a substance has a density of 800 kg/m³ and the density of water is 1000 kg/m³, the Specific Gravity Calculator will provide you with the specific gravity of the substance, which is 0.8.

In the fields of materials science, geology, and fluid dynamics, understanding specific gravity is essential for analyzing the properties of different materials, evaluating mixtures, and predicting how objects will behave when immersed in fluids.
