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