User Guide

This calculator will compare the substance density you have entered with the density of pure water and display the result as a specific gravity decimal ratio. A conversion scale showing SG values for a range of density values will also be displayed, which will change according to the entered density.

1. Enter the density value to be converted in the upper input box.
2. Select the corresponding mass and volumetric units from the upper pair of selection boxes to define the density measurement units.
3. The density will be displayed as a specific gravity ratio in the lower text box.

Formula

The conversion formula used by this tool is:

SG = ρ / ρ₀

Symbols

• ρ = Density of substance in kgm^-3
• ρ₀ = Density of pure water (1000 kgm^-3 @4°C)
• SG = Specific gravity (e.g. pure water = 1)

Density of Substance (ρ)

This is the measure of the amount of mass per unit volume of a substance. The density is derived by dividing the mass of a quantity of substance by its volume.

Specific Gravity of Substance (SG)

This is the ratio of the density of a substance compared to the density of pure water.
