psi to inH2O Conversion Table

Using a standard water density of 1000 kg/m³ at 4 degC and a standard gravity of 9.80665 m/s², pounds per square inch pressure can be displayed in inches of water units with the following conversion factor:

• 1 inH₂O = 249.089 pascals (Pa)
• 1 psi = 6,894.76 pascals (Pa)
• inH₂O value x 249.089 Pa = psi value x 6,894.76 Pa
• inH₂O value = psi value x 27.6799
