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