.4 psi
Inches of water x 0.03613 = psi
Multiply inches of WC by 0.0361 to obtain PSI.
Multiply by 0.036 http://www.enercongroup.com/conversion_factors.htm One PSI is equal to 27.7 inches of water column
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.

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.
20 psi = 555.85 inH2O @39.2 F
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.
0.25 psig = 413.7 inches of water column
Inches of mercury x 0.4912 = psi
