Air Density and Specific Weight
ExplanationDensityDensity is a physical property of matter that refers to the mass amount in a given volume. It is usually expressed in units such as grams per cubic centimetre (g/cm^3) or kilograms per cubic meter (kg/m^3). The density of an object can be calculated by dividing its mass by its volume.

Specific WeightSpecific weight, or unit weight, is a material's weight per unit volume. It is often used in fluid mechanics and soil mechanics to represent the force exerted by gravity on a unit volume of a material. Specific weight can be calculated by multiplying the material's density by the acceleration due to gravity.
