Pressure at altitude diagram
The ambient air pressure at altitide is rougly estimated by assuming an exponential drop with altitiue and a sea-level pressure of 1 atm. In some circumsrtances this method can give large errors, so should not be relied on.

In reality, air pressure is dependant not only on altitude, but on factors such as temperature, relative humidity, and weather conditions. However, this rough estimate can be useful for some non-critical applications.
