## Air density

Density of Air is 1.2 kg/m3 (Rounded value. At sea level, room temperature. Density is in function of the pressure and temperature.). *

Volumetric mass density of Air (air) in other popular units:

= 0.0012 [kg/L] or [g/mL] or [g/cm3] or [t/m3]

= 0.0006936440064 [oz/cu in] (Avoirdupois ounce per cubic inch)

= 0.001251810672 [oz/US fl oz] (Avoirdupois ounce per fluid ounce)

= 4.33527504E-5 [lb/cu in] (Avoirdupois pound per cubic inch)

= 0.0749135532 [lb/cu ft] (pound per cubic foot)

= 2.02266588 [lb/cu yd] (pound per cubic yard)

= 0.01001448534 [lb/US gal] (pound per US liquid gallon)

## Specific gravity (or relative density)

SGw4°C = 0.001200030120756 (relative to 4°C water)

SGair20°C = 0.99659496719542 (relative to 20°C air)
