inH2O to psi Conversion Table

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.
