PSI to mbar, hPa, Bar, inHg, mH2O, inH2O and ftH2O Conversion Table

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 0C, (32F). The mH2O (mWG or mWC), inH2O (inWG or inWC) and ftH2O (ftWG or ftWC) pressure units shown below are for water at 4C (39.2F).
