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

Definition

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

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

Formula

SG = ρhuman body / 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 human body 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 of Human Body (Relative to Water)

Healthy men ranging in age between 20 and 40 fall between:

SG =  1.021 and 1.097

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