Definition
The specific gravity of tar is the ratio of the density of tar to that of a reference substance (Usually water).
This information can be used to tell whether tar will float (or sink) if dropped in water (Buoyancy).
Formula
SG = ρtar / ρwater
Note: Both densities need to be in the same unit as they will cancel each other and produce SG.
