inches of water = 249.08891 pressure (pressure)
Try converting from "in H2O" to atmosphere, bar, barie, barye, inhg (inches of mercury), mmHg (millimeters of mercury), pascal, pieze, psi (pounds per square inch), torr, or any combination of units which equate to "mass / length time squared" and represent calorific value volume basis, draft, energy density, pressure, radiant energy density, sound pressure, stress, vacuum, or volume basis calorific value.
in H2O = .00245832 atmosphere, .00249089 bar, 2,490.89 barie, 2,490.89 barye, .07355592 inhg (inches of mercury), 1.87 mmHg (millimeters of mercury), 249.09 pascal, .24908891 pieze, .03612729 psi (pounds per square inch), 1.87 torr.
