Inches of water x 0.03613 equals pounds per square inch (psi).
10" Water Column equals about .4 Pounds per Square Inch or 0.36127291827412783psi exactly.
That could depend on several different factors, such as altitude etc... I do believe that at about sea level its -14.7 psi.
Inches of mercury x 0.4912 = psi
If it is fresh water, and the surface is at sea level, then the pressure at the surface is 14.69 psi. As you submerge, then the pressure from the weight of the water above you is added to the air pressure above the water. For each foot that you descend, the water pressure will increase by 0.4331 psi, so at 328 feet deep, the water pressure is 142.0568 psi. Add the 14.69 psi air pressure to get 156.7468 psi.
27.7 inches
27.71 inches of water column equals 1 psi
Inches of water x 0.03613 = psi
Inches of water x 0.03613 equals pounds per square inch (psi).
35 inches of water = 1.26 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.
Multiply inches of WC by 0.0361 to obtain PSI.
Pressure doesn't change when you change substance, 120 PSI in water equals 120 PSI in air.
10" Water Column equals about .4 Pounds per Square Inch or 0.36127291827412783psi exactly.
Multiply by 0.036 http://www.enercongroup.com/conversion_factors.htm One PSI is equal to 27.7 inches of water column
About 130 psi at 300 feet of water depth.
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.
