What is Inches Of Water To PSI?
Definition:
Inches of water (inH2O) is a unit of pressure commonly used in low-pressure applications such as HVAC and fluid dynamics, while psi (pounds per square inch) is widely utilized in various industries for measuring pressure.
How to Convert Inches Of Water To PSI?
Example Problem:
The following example outlines the steps and information needed to perform the conversion.
First, determine the inches of water. In this example, there were 10 inches of water measured.
Next, calculate the pressure by multiplying the inches of water by the conversion factor 0.03612629.
Finally, apply the formula above:
psi = inH2O * 0.03612629
psi = 10 * 0.03612629
psi โ 0.361263
