This calculator is based on the 1976 model of the U.S. Standard Atmosphere (NASA-TM-X-74335).
Two input options are modeled, you can either provide:
- altitude and ambient temperature
- altitude and temperature offset (from Std. Atm.)
Disclaimer (the simple version):
I have made every effort to ensure that all the calculations that form part of this tool are correct and accurate, I have back-tested it and validated it against the NASA-TM-X-74335 report. HOWEVER, I cannot and do not guarantee that the results output from the calculator are correct. You should always double check the results being output – especially if you are using the results for engineering calculations. Finally, if you do discover any bugs in the calculations I would really appreciate it if you would drop me an email at firstname.lastname@example.org and let me know so I can make the correction.
