What Is This Tool?
This converter allows you to change pressure values from pound-force per square inch (psi), an imperial pressure unit commonly used in mechanical systems, to inch mercury (32°F) [inHg], a manometric pressure unit mainly applied in atmospheric, vacuum, and aviation measurements.
How to Use This Tool?
-
Enter the pressure value in pound-force per square inch (psi) to be converted

Examples
-
Convert 5 psi: 5 × 2.0360258722 = 10.180129361 inHg
-
Convert 10 psi: 10 × 2.0360258722 = 20.360258722 inHg
Common Use Cases
-
Checking automotive tire pressure and engine diagnostics
-
Reporting atmospheric pressure and altimeter settings in aviation and meteorology
-
Measuring vacuum levels in HVAC, refrigeration, and laboratory environments
-
Comparing hydraulic or pneumatic system pressures to atmospheric or vacuum references
Tips & Best Practices
-
Ensure unit consistency when working with mechanical systems and atmospheric measurements
-
Be aware the inch mercury unit assumes standard temperature of 32°F
-
Use this tool to bridge between psi and inHg for clearer communication across different fields
-
Cross-check conversions when precise pressure readings are critical
Limitations
-
Conversion assumes standard temperature conditions of 32°F for inch mercury
-
Local gravity or temperature variations can impact inHg measurement accuracy
-
Psi is typical in mechanical contexts, while inHg is common in atmospheric and vacuum readings, so careful application is needed
-
This converter does not account for temperature or gravitational differences outside standard conditions
Frequently Asked Questions
-
What does pound-force per square inch measure?
-
Pound-force per square inch (psi) measures pressure as one pound-force applied over an area of one square inch. It is widely used in engineering and automotive contexts.
-
What is inch mercury (32°F) used for?
-
Inch mercury (32°F) is a manometric pressure unit representing the pressure exerted by a one-inch column of mercury at 32°F, commonly used in meteorology, aviation, HVAC, and vacuum measurements.
-
Can I convert any psi value directly to inHg with this tool?
-
Yes, you can convert any psi value to inch mercury (32°F) with this converter, keeping in mind it assumes standard temperature conditions for accuracy.
Key Terminology
-
Pound-force per square inch (psi)
-
An imperial pressure unit describing one pound-force applied to an area of one square inch, frequently used in engineering and automotive industries.
-
Inch mercury (32°F) [inHg]
-
A manometric pressure unit defined by the pressure from a one-inch column of mercury at 32°F under standard gravity, often used in meteorology, aviation, and vacuum systems.
