2022: ☢️ Specific Gravity of Petrol (& Formula, Definition, Infographic)

Definition

The specific gravity of petrol is the ratio of the density of petrol to that of a reference substance (Usually water).

This information can be used to tell whether petrol will float (or sink) if dropped in water (Buoyancy).

Formula

SG = ρpetrol / ρwater

Note: Both densities need to be in the same unit as they will cancel each other and produce SG.

Specific Gravity vs Density vs Specific Weight

There are important differences between density, specific weight and specific gravity. Follow these links to learn about the differences between them.

I will provide you the petrol specific gravity in a dimensionless unit (Unitless) in this page. You may check how it converts to kg/m³ (SI unit), g/cm³, g/ml, kg/l, lb/ft³ by following the link below:

Specific gravity values are not very useful. Why not check the density of petrol (all units)?
