Formula
Formula
Pa = µbar × 0.1
Multiply any value in microbar (vacuum) by 0.1 to obtain the value in pascals (vacuum).
Worked example
Convert 100 µbar to Pa.
- 01Start with 100 µbar.
- 02Multiply by the conversion factor: 100 × 0.1 = 10 Pa.
Result100 µbar = 10 Pa

FAQ
What is the conversion factor from µbar to Pa?
1 µbar equals 0.1 Pa. To convert, multiply the value in microbar (vacuum) by 0.1.
How do I convert 1 µbar to Pa?
1 µbar = 0.1 Pa. For any value, multiply by 0.1.
How do I convert Pa back to µbar?
Divide by the same factor — or equivalently, multiply by 10. So 1 Pa = 10 µbar.
When would I need to convert microbar (vacuum) to pascal (vacuum)?
Vacuum-pressure conversions between µbar and Pa 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).
