# Relative Density Calculator

## About Relative Density Calculator (Formula)

A Relative Density Calculator, also known as specific gravity calculator, is a tool used in physics and engineering to calculate the relative density or specific gravity of a substance. Relative density compares the density of a substance to the density of a reference substance, usually water. This calculation is important for determining the buoyancy of objects in different fluids and for understanding the properties of materials. The formula used to calculate relative density involves the density of the substance and the density of the reference substance.

The formula for calculating relative density (RD) or specific gravity of a substance with density (ρ) relative to the density of the reference substance (ρ₀) is:

Relative Density (RD) = ρ / ρ₀

Where:

• Relative Density (RD) is the ratio of the density of the substance to the density of the reference substance.
• ρ is the density of the substance.
• ρ₀ is the density of the reference substance (usually water at a standard temperature).

Using the Relative Density Calculator involves these steps:

1. Input: Enter the density of the substance and the density of the reference substance into the calculator.
2. Calculation: The calculator applies the formula to calculate the relative density.
3. Output: The calculator displays the calculated relative density.

This tool is particularly useful for physicists, chemists, engineers, and researchers who need to understand the properties and behaviors of materials in different environments.

For example, if the density of a substance is 800 kg/m³ and the density of water (reference substance) is 1000 kg/m³, the Relative Density Calculator will provide you with the relative density of the substance.

In the fields of fluid mechanics, materials science, and chemistry, relative density calculations are crucial for understanding buoyancy, designing objects to float or sink, and characterizing material properties.
