Specific Gravity of River Sand 🪨 (& Formula, Definition, Infographic) rev. 2022

Definition

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

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

Formula

SG = ρriver sand / 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 river sand 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 river sand (all units)?
