Rendered to 6 significant figures.
Formula
Formula
kPa = Torr × 0.1333224
Multiply any value in torr (vacuum) by 0.1333224 to obtain the value in kilopascals (vacuum).
Worked example
Convert 760 Torr to kPa.
- 01Start with 760 Torr.
- 02Multiply by the conversion factor: 760 × 0.1333224 = 101.325 kPa.
Result760 Torr = 101.325 kPa

FAQ
What is the conversion factor from Torr to kPa?
1 Torr equals 0.1333224 kPa. To convert, multiply the value in torr (vacuum) by 0.1333224.
How do I convert 1 Torr to kPa?
1 Torr = 0.133322 kPa. For any value, multiply by 0.1333224.
How do I convert kPa back to Torr?
Divide by the same factor — or equivalently, multiply by 7.500617. So 1 kPa = 7.50062 Torr.
When would I need to convert torr (vacuum) to kilopascal (vacuum)?
Vacuum-pressure conversions between Torr and kPa are common in vacuum-chamber instrumentation, pump-down endpoint specification, semiconductor and deposition process work, freeze-drying, electron-microscopy column pressure, vacuum metallurgy and HVAC / refrigeration service. Torr, mmHg and inHg dominate manometric vacuum gauges; mbar is standard on European instruments; micron Hg and mTorr cover high-vacuum work; Pa and kPa are the SI references. This category is vacuum / instrumentation intent — dimensionally the same as pressure, but kept separate so process-pressure searches and vacuum searches stay on the right page.
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).
