text: The US Standard Atmosphere (USSA) uses 8.31432 m3·Pa/(mol·K) as the value of R.
text: This air pressure, density, and temperature vs. altitude calculator determines the atmospheric pressure, air density, temperature and the speed of sound for a given altitude and a temperature offset using the International Standard Atmosphere (ISA) and the US Standard Atmosphere 1976 (USSA) models, which are essentially the same in the interval of 0–86 km.
text: The main difference between the US Standard Atmosphere (USSA) and ISA is mainly in the assumed temperature distribution at higher altitudes, which are not covered in this converter.
text: The US Standard Atmosphere (USSA) uses 8.31432 m3·Pa/(mol·K) as the value of R (see Gas constant) for all calculations.
