PSI to GPM Calculator
We programmed PSI to GPM Calculator to convert Pounds per Square Inch (PSI) to Gallons per Minute (GPM). PSI measures pressure, while GPM quantifies flow rate.

Can you convert PSI to gpm?
Converting PSI to GPM is not a straightforward process, as these units measure different properties (pressure and flow rate, respectively).
The conversion requires additional information, such as the size of the pipe or orifice through which the fluid is flowing.
We can use the concept of hydraulic horsepower to find the relationship between PSI and GPM.
Hydraulic horsepower is calculated using both PSI and GPM:
Hydraulic Horsepower = (PSI × GPM) ÷ 1714For example, if we have a system operating at 3000 PSI and want to achieve 20 hydraulic horsepower, we can calculate the required GPM:
20 = (3000 × GPM) ÷ 1714
GPM = (20 × 1714) ÷ 3000
GPM ≈ 11.43
PSI to GPM Conversion Formula
The hydraulic horsepower formula to solve for GPM when PSI and horsepower are known:
GPM = (Hydraulic Horsepower × 1714) ÷ PSILet’s say we want to achieve 30 hydraulic horsepower at 3500 PSI:
GPM = (30 × 1714) ÷ 3500
GPM ≈ 14.69
This formula allows us to calculate the flow rate (GPM) needed to achieve a specific hydraulic horsepower at a given pressure (PSI).
