FAQ
What is the conversion factor from Torr to mbar?
1 Torr equals 1.333224 mbar. To convert, multiply the value in torr by 1.333224.
How do I convert 1 Torr to mbar?
1 Torr = 1.33322 mbar. For any value, multiply by 1.333224.
How do I convert mbar back to Torr?
Divide by the same factor — or equivalently, multiply by 0.7500617. So 1 mbar = 0.750062 Torr.
When would I need to convert torr to millibar?
Pressure conversions between Torr and mbar 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).
