Using a standard water density of 1000 kg/m³ at 4 degC and a standard gravity of 9.80665 m/s², an meters 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 mH
_{2}O = 9,806.65 pascals (Pa) - psi value x 6,894.76 Pa = inH
_{2}O value x 9,806.65 Pa **psi value = mH**_{2}O value x 1.42233
