What is specific gravity?

Specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water.

How is density calculated?

Density is calculated using the formula: Density = Mass/Volume. You can also convert from specific gravity using the density of water.

The density of water is essential for converting specific gravity to density; it provides a baseline value for calculations.

Density is commonly expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

To convert specific gravity to density, you need the specific gravity (SG) value and the density of water (typically 1 g/cm³ or 1000 kg/m³). Use the formula: Density = SG × Density of Water. For example, if the specific gravity is 2 and the density of water is 1000 kg/m³, then the density is 2 × 1000 = 2000 kg/m³.
