About these units
One standard atmosphere is the mean sea-level air pressure, defined as 101.325 kilopascals or about 14.7 psi. Vacuum and process engineering reference it as a baseline.
Pounds per square inch is the standard US pressure unit for compressed air, hydraulics, and tire and vessel ratings. Shop air systems typically run 90 to 125 psi.
