What is Specific Gravity?

Expand Hint
Water is commonly referenced when determining specific gravity.
Hint 2
Also known as Relative Density.
Specific Gravity, or Relative Density, is the ratio of a substance's density to a given reference material density. For liquids, water is commonly referenced. For gases, room temperature air is typically baselined.
$$$RD=\frac{\rho _{substance}}{\rho _{reference}}$$$
