## Air 20°C density

Density of the air depends of the pressure and temperature. Very common value used in calculation for relative density of gases, is the density of the air at room temperature, which is approx 20°C (68°F).

Density of Air 20°C is 1.2041 kg/m3 (at 1 atm or 101.325 kPa pressure). *
