Convert feet of head to PSI for water pressure, pump systems, plumbing lines, pressure tanks, irrigation systems, and static head calculations. This calculator also shows meters of head, kPa, bar, adjusted outlet pressure, and pressure difference from a target.
Head to PSI:
The calculator divides feet of head by 2.31 to estimate water pressure in PSI.
Adjusted PSI:
The calculator subtracts head loss and elevation change from available head, then converts the remaining head to PSI.
Pressure difference:
The calculator compares available pressure to a target pressure.
This calculator helps convert pump head, static head, or water column height into PSI for plumbing and water system planning.
It can help compare feet of head, meters of head, PSI, kPa, bar, adjusted pressure, head loss, elevation change, and target pressure.
Your result shows estimated PSI from feet of head. It can also show adjusted PSI after head loss and elevation change. These values are planning estimates for water. Real systems can vary based on pipe friction, fittings, valves, filters, pump performance, elevation, and fixture demand.
One foot of water head is about 0.433 PSI.
Divide feet of head by 2.31. For example, 138.6 feet of head divided by 2.31 equals 60 PSI.
Feet of head is often used for pumps and water elevation, while PSI is commonly used for plumbing pressure and fixtures.
This calculator uses a standard water conversion. Actual system pressure can vary with fluid type, temperature, pipe friction, fittings, elevation, and system layout.
