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.
The megapascal equals one million pascals, or one newton per square millimeter. Material strengths such as yield and tensile are published in megapascals.
