Calculate static water pressure from elevation height, water column height, tank height, or feet of head. Estimate PSI, kPa, bar, meters of head, outlet pressure, pressure gain, pressure loss, and target pressure difference for plumbing, irrigation, tanks, pumps, and water supply planning.
Height to pressure:
The calculator converts water height or elevation into static pressure using feet of water divided by 2.31.
Pressure to height:
The calculator converts known pressure into an equivalent water column height using PSI multiplied by 2.31.
Outlet pressure:
The calculator adds or subtracts elevation pressure and subtracts friction loss from starting pressure.
Tank pressure:
The calculator estimates pressure at the bottom outlet of a tank based on water depth above the outlet.
A static water pressure calculator helps estimate pressure from elevation, gravity-fed tanks, water columns, storage tanks, and pump head.
It can help compare PSI, feet of head, meters of head, kPa, bar, pressure gain, pressure loss, outlet pressure, and target pressure.
Your result shows estimated static water pressure from height or elevation. Static pressure is the pressure when water is not flowing. When water is flowing, actual outlet pressure can be lower because of pipe friction, fittings, valves, filters, elevation changes, and fixture demand.
Static water pressure is pressure in a water system when water is not flowing. It can come from supply pressure, elevation, or the height of water above an outlet.
One foot of water creates about 0.433 PSI of static pressure.
For water, 40 PSI requires about 92.4 feet of head because 40 × 2.31 = 92.4 feet.
No. Static pressure is measured when water is not moving. Flowing pressure can be lower because water loses pressure through pipe friction, fittings, valves, filters, and fixtures.
