Centimeters of Water

Term Category: Physics

Centimeters of water (Cm H2O) is a unit of pressure measurement. It is used to quantify pressure in terms of the height of a column of water. One centimeter of water is equal to the pressure exerted by a one-centimeter high column of water under the influence of gravity at standard conditions. Phonation Threshold Pressure is generally between 1 and 3 centimeters of water.
