Why is Inches of Water a Unit of Pressure?

Pressure, a fundamental concept in physics and engineering, is typically measured in units such as Pascals (Pa), pounds per square inch (psi), or atmospheres (atm). However, in certain contexts, especially in the measurement of low pressures or in specific industries like HVAC (heating, ventilation, and air conditioning) and water treatment, inches of water (inH2O) emerge … Read more
