PHYIC CALCULATOR
Specific Gravity Calculator
A precise tool.
What is the Specific Gravity Calculator & How does it work?
Specific gravity (SG) is a dimensionless quantity that compares the density of a substance to the density of water at a specified temperature. It is commonly used in various fields such as engineering, geology, and chemistry.
The specific gravity of a substance can be calculated using the formula:
SG = frac{rho_{substance}}{rho_{water}}
SG = Specific Gravity, rho_{substance} = Density of the substance, rho_{water} = Density of water
The density of water is typically taken as 1 g/cm³ at 4°C for most practical purposes.

Frequently Asked Questions
What is specific gravity?
Specific gravity is a dimensionless quantity that compares the density of a substance to the density of water at a specified temperature, typically 4°C.
How do I use this specific gravity calculator?
Enter the density of the substance and the density of water (usually 1 g/cm³ at 4°C) into the calculator to find the specific gravity.
Why is the temperature for water’s density specified as 4°C?
Water has its maximum density at 4°C, making it a standard reference point for calculating specific gravity.
Can I use this calculator for gases?
This calculator is primarily designed for liquids. For gases, you would need to consider the specific gas laws and conditions.
What units should I use for density when calculating specific gravity?
You can use any consistent units for density as long as both the substance’s density and water’s density are in the same units.
How does specific gravity relate to buoyancy?
Specific gravity is related to buoyancy through Archimedes’ principle. If a substance’s specific gravity is less than 1, it will float; if greater than 1, it will sink in water.
Is specific gravity the same as relative density?
Yes, specific gravity and relative density are synonymous terms used to describe the ratio of a substance’s density to that of water.
