FAQ
What is the conversion factor from inHg to Pa?
1 inHg equals 3386.389 Pa. To convert, multiply the value in inches of mercury (0 °C) by 3386.389.
How do I convert 1 inHg to Pa?
1 inHg = 3386.39 Pa. For any value, multiply by 3386.389.
How do I convert Pa back to inHg?
Divide by the same factor — or equivalently, multiply by 0.0002952998. So 1 Pa = 0.0002953 inHg.
When would I need to convert inch of mercury (0 °C) to pascal?
Pressure conversions between inHg and Pa 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).
