If you use a standard water density of 1000 kg/m³ at 4 degC and standard gravity of 9.80665 m/s², then pound force per square inch pressure can be converted to a hydrostatic level in feet using the following calculation:
- 1 ftH2O = 2,989.07 pascals (Pa)
- 1 psi = 6,894.76 pascals (Pa)
- ftH2O value x 2,989.07 Pa = psi value x 6,894.76 Pa
- ftH2O value = psi value x 2.30666
Enter a pressure in psi below to convert it to the equivalent pressure in ftH₂O 4°C.
Choose a value between 0 and 1000 psi from the pressure conversion table below, to obtain the converted value in ftH₂O 4°C.
