The value for the density of air at STP (Standard Temperatureand Pressure) depends on the definition of STP. The definition of the temperature and pressure isn't standard, so the value depends on who you consult. The ISA or International Standard Atmosphere states the density of air is 1.225...
Because of these dependencies and the fact that the Earth's atmosphere contains various gases (mostly nitrogen, oxygen, argon and water vapor) the air density definition needs to be further expanded. A proper modification has been made in our air density calculator with the density of air formul...
The ratio of the density of the air at a given altitude to the air density at the same altitude in a standard atmosphere. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. ...
Specific Gravity of gasesis normally calculated with reference to air - and defined asthe ratio of the density of the gas to the density of the air- at a specified temperature and pressure. The Specific Gravity can be calculated as SG = ρgas/ ρair(3) where SG = specific gravity of g...
At sea level and at 15 °C, air has a density of approximately 1.225 kg/m3 (0.001225 g/cm3, 0.0023769 slug/ft3, 0.0765 lbm/ft3) according to ISA (International Standard Atmosphere).Specific weight and density of air at standard atmospheric pressure - Imperial Units: ...
The meaning of DENSITY ALTITUDE is the altitude that corresponds to a given air density in a standard atmosphere.
yahoo "standard atmosphere" ...there a lots of tables you can copy, some refs may have equations ...you'll probably need to remember high school chemistry to correct for your non-standard temperaturesgood luck Matador (Mechanical) (OP) 13 May 05 15:59 I have not been able to find ...

Online calculator, figures and tables showing density, specific weight and thermal expansion coefficients of air at temperatures ranging -100 to 1600 °C (-140 to 2900 °F) at atmospheric and higher pressure - Imperial and SI Units.
As an example let us calculate the density of dry air at sea level in international standard atmosphere conditions of pressure (1013.25hPaor 101325Pa) and temperature (15oC). Remember that to convertoCtooKyou need to add 273.15. Density = 101325 / (287.05 * (15 + 273.15)) = 1.225 kg/m3...
