Inch of H2O-inH2O

Inch of water (inH2O) is a unit of pressure representing the hydrostatic pressure exerted by a column of water one inch high. It is commonly used to measure low pressures, particularly in applications involving air and other gases. The precise value of inH2O depends on the temperature and density of the water, but it is typically referenced to water at 4 degrees Celsius for standardization.
