FAQ

What is the conversion factor from bar to inHg?
1 bar equals 29.52998 inHg. To convert, multiply the value in bar by 29.52998.
How do I convert 1 bar to inHg?
1 bar = 29.53 inHg. For any value, multiply by 29.52998.
How do I convert inHg back to bar?
Divide by the same factor — or equivalently, multiply by 0.03386389. So 1 inHg = 0.0338639 bar.
When would I need to convert bar to inch of mercury (0 °C)?
Pressure conversions between bar 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).
