Air Pressure vs Altitude and Breathing, on Excel
Simple Excel spreadsheet gives air pressure given altitude, or altitude given air pressure, in common SI and IP units.
Also gives a simple percentage estimate of the additional breathing (volume of air that must be inhaled, the work to breathe) that must be done to obtain an equal amount of oxygen compared to breathing at sea level.
No macros. No VBA.
