This question cannot be answered sensibly. A pound per square inch is a measure of pressure, with dimensions [ML-2]. A pound is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

You cannot convert gallons per minute to pounds per square inch. The quantities do not have the same meaning. Gallons are a measure of volume, and pounds are a measure of weight. Minutes are a measure of time, and square inches are a measure of area.

The answer will depend on what it is that you wish to convert into PSI. You cannot. Inches are a linear measure, PSI (pounds per square inch) is a measure of pressure. The units are incompatible.
MPa x 145 = psi
