Convert pound/square inch to millimeter water [4 °C]


PSI
millimeter water

The above form works if you are measuring differential pressure, such as the difference in psi between two points. It also gives the correct answer for absolute pressure, assuming you are measuring psia, which is the pressure relative to absolute zero vacuum.

If you are measuring relative to vacuum and want to resolve the pressure relative to the atmosphere, then you should use the form below.

PSI (relative to atmosphere)
millimeter water (relative to vacuum)
