## 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.

- Enter the density value to be converted in the upper input box.
- Select the corresponding mass and volumetric units from the upper pair of selection boxes to define the density measurement units.
- 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 / ρ_{0}

###### Symbols

- ρ = Density of substance in kgm
^{-3} - ρ
_{0}= 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.
