Using a standard water density of 1000 kg/m³ at 4 degC and a standard gravity of 9.80665 m/s², an inches of water column pressure value can be displayed in pounds per square inch pressure units with the following conversion factor:
- 1 psi = 6,894.76 pascals (Pa)
- 1 inH2O = 249.089 pascals (Pa)
- psi value x 6,894.76 Pa = inH2O value x 249.089 Pa
- psi value = inH2O value x 0.0361273
Enter a pressure in inH₂O 4°C below to convert it to the equivalent pressure in psi.
Choose a value between 0 and 100 inH₂O 4°C from the pressure conversion table below, to obtain the converted value in psi.
