WebISA (International Standard Atmosphere) and 1976 U.S. Standard Atmosphere define air density at the standard pressure 1013.25 hPa and temperature 15 °C as 1.225 kg/m³ or 0.0765 lb/ft³. Air density is affected not only by the temperature and pressure but also by the amount of water in the air. The more water vapor is contained in the air, the ... WebThe reference temperature is the standard temperature of 15°C (59°F). The reference pressure is the standard pressure of 1013.25 mb (29.92 inHg). These values are used to calculate the temperature, pressure, and density of the atmosphere at different altitudes.
