One psi makes a column of Mercury rise 51.71 millimeters, based on the measurement that one psi is approximately 6.894 KPa. This is equivalent to 0.00328 feet.

5.4 feet = 164.6 centimeters (cm)
About 2 1 pound per square inch = 2.0362... inches of mercury
A water barometer would have to be many feet tall because the density of water is much lower than that of mercury. In addition, the vacuum above the column would be spoiled by the water vapor pressure, far higher than that of mercury, and strongly temperature dependent.
Pressure in these things is measured by how tall a column of liquid it can support. Now atmospheric pressure can support many feet of oil, for example, and who wants a barmeter that tall? Mercury is very dense so you can get away with less than a metre high. Problem solved.
