Rendered to 6 significant figures.
Formula
Formula
kPa = µbar × 0.0001
Multiply any value in microbar (vacuum) by 0.0001 to obtain the value in kilopascals (vacuum).
Worked example
Convert 100000 µbar to kPa.
- 01Start with 100000 µbar.
- 02Multiply by the conversion factor: 100000 × 0.0001 = 10 kPa.
Result100000 µbar = 10 kPa

FAQ
What is the conversion factor from µbar to kPa?
1 µbar equals 0.0001 kPa. To convert, multiply the value in microbar (vacuum) by 0.0001.
How do I convert 1 µbar to kPa?
1 µbar = 0.0001 kPa. For any value, multiply by 0.0001.
How do I convert kPa back to µbar?
Divide by the same factor — or equivalently, multiply by 10000. So 1 kPa = 10000 µbar.
When would I need to convert microbar (vacuum) to kilopascal (vacuum)?
Vacuum-pressure conversions between µbar 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).
