FAQ
What is the conversion factor from bar to mmHg?
1 bar equals 750.0616 mmHg. To convert, multiply the value in bar by 750.0616.
How do I convert 1 bar to mmHg?
1 bar = 750.062 mmHg. For any value, multiply by 750.0616.
How do I convert mmHg back to bar?
Divide by the same factor — or equivalently, multiply by 0.001333224. So 1 mmHg = 0.00133322 bar.
When would I need to convert bar to millimetre of mercury?
Pressure conversions between bar and mmHg 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).
