Convert pressure units including PSI, PSF, pascals, kPa, MPa, bar, atmospheres, torr, inches of water, feet of head, and inches of mercury.
PSI to kPa:
1 PSI = 6.89476 kPa
PSI to bar:
1 PSI = 0.0689476 bar
PSI to feet of head:
1 PSI = 2.30666 ft H₂O
Feet of head to PSI:
1 ft H₂O = 0.4335 PSI
Pressure conversions are useful for plumbing, water pressure, pumps, irrigation, hydronic heating, pressure tanks, air compressors, pipe systems, drainage, engineering, and construction estimates.
Use this converter when switching between PSI, metric pressure units, water head, atmospheric pressure, and pressure gauge references.
Your result shows the entered pressure converted from the starting unit into the selected ending unit. The converter also shows common references such as PSI, kPa, bar, and feet of head.
This converter changes pressure units only. Actual system performance depends on pipe size, elevation, flow rate, pump capacity, friction loss, valves, fittings, and equipment ratings.
Multiply PSI by 6.89476. For example, 50 PSI equals about 344.738 kPa.
1 PSI equals about 2.30666 feet of water head.
Multiply feet of head by 0.4335. For example, 100 feet of head equals about 43.35 PSI.
PSI is a pressure unit. Water pressure is often measured in PSI, but it can also be expressed in kPa, bar, or feet of head.
No. This converter only changes pressure units. Pressure drop depends on pipe length, pipe diameter, fittings, flow rate, fluid type, and pipe roughness.
