Convert pump head into pressure. Enter pump head in feet or meters and calculate PSI, kPa, bar, pascals, atmospheres, and equivalent water pressure for pump, well, tank, irrigation, and plumbing systems.
Pump head:
Enter the pump head value from a pump curve, pump rating, system estimate, or water column height.
Liquid density:
Select fresh water or another liquid. The same head creates different pressure when liquid density changes.
Pressure result:
The calculator converts pump head into pressure using density, gravity, and head height.
A pump head to PSI calculator is useful for wells, irrigation systems, booster pumps, water tanks, pressure systems, pool pumps, plumbing estimates, and comparing pump curves to pressure requirements.
Pump head is often listed in feet or meters, while pressure gauges usually show PSI, kPa, or bar.
The general pump head pressure formula is:
P = ρ × g × h
For fresh water, divide feet of head by about 2.31. For example, 100 feet of head is about 43.35 PSI.
For fresh water, 50 feet of pump head is about 21.65 PSI.
For fresh water, 1 PSI is about 2.31 feet of head.
No. Pump head is a height measurement, while pressure is force per area. They are related through liquid density and gravity.
