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