Inches Of Water To Psi Formula
The following equation is used to convert inches of water to psi.
psi = inH2O * 0.03609
- Where psi is the pressure in pounds per square inch (psi)
- inH2O is the pressure measured in inches of water (inH2O)
- 0.03609 is the conversion factor
To convert inches of water to psi, multiply the inches of water by 0.03609.

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 0.03609.
Finally, apply the formula above:
psi = inH2O * 0.03609
psi = 10 * 0.03609
psi = 0.3609
FAQ
What is the conversion factor used in this calculator?
