psi to Inches of Water Conversion
Use our psi to inches of water conversion tool to convert pressure in pounds per square inch to inH₂O.
What psi to Inches of Water Conversion does
This tool converts pressure readings from pounds per square inch (psi) to inches of water (inH₂O). Users enter a numerical psi value and receive the equivalent inH₂O measurement, providing a standardized way to compare pressure values across different systems. The output is useful for HVAC work, engineering calculations, and any situation requiring fluid pressure standardization. The site also supports reverse conversions and offers a wide selection of other pressure units beyond the default pair. The interface presents the conversion formula and examples, such as converting 8 psi to inH₂O, directly on the page. A “Share result” button and options to reload or clear the calculator are included for convenience. Compared to manual lookup tables, this tool delivers instant, accurate results without requiring the user to track conversion factors. It also distinguishes between PSI (gas/liquid pressure) and inches of water (static pressure measurement), clarifying the physical meaning of each unit.

psi to Inches of Water Conversion FAQ
- Can I convert from inches of water back to psi?
- Yes, the tool supports reverse conversion. Enter a value in inches of water (inH₂O) and the calculator will return the equivalent in pounds per square inch (psi).
- What is the formula used for psi to inches of water conversion?
- The conversion is based on the relationship between psi and inH₂O, where 1 psi approximately equals 27.68 inches of water. The exact factor depends on temperature and gravity assumptions.
- Is this tool accurate for HVAC static pressure measurements?
- It provides a reliable standard conversion for typical HVAC static pressure readings. For precise system design, verify that your specific fluid and temperature conditions match the tool's assumptions.
- Can I convert to units other than psi and inches of water?
- Yes, the calculator includes a list of additional pressure units. You can select any unit from the dropdown to convert from your input value.
