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.
