*Liters per minute (LPM) cannot be directly converted to pounds per square inch (PSI) because they measure different properties. LPM measures flow rate, while PSI measures pressure. The conversion would require additional information, such as the size of the system, the type of fluid, and the system’s characteristics, to determine the PSI corresponding to a specific LPM.*
