The si derived unit for pressure is the pascal.
Inches of water column vacuum gauge.
The units are conventionally used for measurement of certain pressure differentials such as small pressure differences across an orifice or in a pipeline or shaft.

1 pascal is equal to 0 0040146307866177 inch of water column or 0 00014503773800722 psig.
Vacuum or vacuum pressure measurements are described as either absolute or relative.
Inches of water is a non si unit for pressure.
These low pressures are most often read using a manometer or a magnahelic gauge.
Pressure measurements given in inches or millimeters of water mercury or some other liquid are based on the earliest instrument developed for measuring pressure the liquid column gauge or manometer.
1 psi is equal to 27 71 inches of water column.
This scale is still in use today usually shown as 0 to 30 inches of hg on gauges such a bourdon dial gauges.
This simple gauge measures the difference in the levels of the mercury from 0 inches at atmospheric pressure up to 29 92 inches of hg at the best vacuum attainable.

It is also given as inches of water gauge iwg or in w g.
This is why water column is most often used to measure pressures under 1 psi.
So the water columnis 13 534 times as high as the mercury column at the same pressure.

While some water manometers water tube are still in use the vast majority are either dial or digital gauges that still use the same scale.
