27.71 inches of water column equals 1 psi
1 psig is equivalent to 51.71 mm (2 in) of mercury or to approx 700 mm (27.5 in) of water. Technically one cannot have apsig. Psig represents a pressure reading of the pressure above normal atmospheric pressure of 14.7 psi. You mean a psi.
10" Water Column equals about .4 Pounds per Square Inch or 0.36127291827412783psi exactly.

0.25 psig = 413.7 inches of water column
10 psi.
12.01 psi
For water, a 60 ft vertical change is equivalent to about 26 psi change. So if the pressure is 60psi at the bottom, it will be 34 psi at the top. See related link.
About 2 1 pound per square inch = 2.0362... inches of mercury
Head pressure is created by a column (depth) of water in a container. Pipe is considered a container. Diameter is not a factor. The higher the column of water, the more psi it creates. Multiply column height of water by .434 to get psi of water.

One psi (pounds per square inch) is 27.7 inches of water. An inch of water is a unit of pressure which will raise water one inch. A cubic inch of water weighs 0.0361 pounds, so one psi is one over 0.0361 or 27.7 inches of water.
Multiply inches of WC by 0.0361 to obtain PSI.
