Solution
The terms specific gravity and specific weight are used for relative density.
The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ. For instance a commonly used value is the specific weight of water on Earth at 5°C which is 62.43 lbf/ft3 or 9807 N/m3. While
Specific Gravity is the ratio of the density of water to the density of another substance. Because of being a ratio of two similar quantities it has no unit.
