FAQ

What is the conversion factor from Pa to inHg?
1 Pa equals 0.0002952998 inHg. To convert, multiply the value in pascals by 0.0002952998.
How do I convert 1 Pa to inHg?
1 Pa = 0.0002953 inHg. For any value, multiply by 0.0002952998.
How do I convert inHg back to Pa?
Divide by the same factor — or equivalently, multiply by 3386.389. So 1 inHg = 3386.39 Pa.
When would I need to convert pascal to inch of mercury (0 °C)?
Pressure conversions between Pa and inHg are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
