Look up a pressure in pounds per square inch to find the conversion value in mb, hPa, bar, inches of mercury, metres of water column/gauge, inches of water column/gauge or feet of water column / gauge.
Alternatively you can use the pressure unit converter to calculate the equivalent psi value in other units.
The inHg pressure units shown below are for mercury at 0°C, (32°F). The mH2O (mWG or mWC), inH2O (inWG or inWC) and ftH2O (ftWG or ftWC) pressure units shown below are for water at 4°C (39.2°F).
