Description

Inch of Water (inH₂O): HVAC and Fluid Mechanics

The Inch of Water (inH₂O) is a unit of pressure defined as the pressure exerted by a column of water one inch high, approximately equal to 249.0889 Pascals. It is widely used in the HVAC industry to measure air pressure in ducts and ventilation systems, as well as in fluid mechanics for low-pressure measurements.

Millimeter of Water (mmH₂O): Low-Pressure Measurements

The Millimeter of Water (mmH₂O) is a unit of pressure equal to the pressure exerted by a column of water one millimeter high. It is approximately equal to 9.80665 Pascals. This unit is used in various applications requiring the measurement of small pressure differences, such as in ventilation systems and laboratory experiments.
