Air Density is the mass per unit volume of the air. For example, the standard air density at sea level is 1.225 kg/m 3 (0.076474 pounds/ft 3). Relative Density is the ratio of the actual air density to the standard sea level density, expressed as a percentage.
However, air typically contains a lot of water vapor, which would make it more dense than the cited value. Answer: The density of dry air is 1.29 grams per liter (0.07967 pounds per cubic foot) at 32Â° Fahrenheit (0Â° Celsius) at average sea level barometric pressure (29.92 inchs of mercury or 760 millimeters).
