FAQ
What is the conversion factor from µbar to mPa?
1 µbar equals 100 mPa. To convert, multiply the value in microbar (vacuum) by 100.
How do I convert 1 µbar to mPa?
1 µbar = 100 mPa. For any value, multiply by 100.
How do I convert mPa back to µbar?
Divide by the same factor — or equivalently, multiply by 0.01. So 1 mPa = 0.01 µbar.
When would I need to convert microbar (vacuum) to millipascal (vacuum)?
Vacuum-pressure conversions between µbar and mPa 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).
