About these units
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.
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.
