FAQ
What is the conversion factor from Pa to µm Hg?
1 Pa equals 7.500617 µm Hg. To convert, multiply the value in pascals (vacuum) by 7.500617.
How do I convert 1 Pa to µm Hg?
1 Pa = 7.50062 µm Hg. For any value, multiply by 7.500617.
How do I convert µm Hg back to Pa?
Divide by the same factor — or equivalently, multiply by 0.1333224. So 1 µm Hg = 0.133322 Pa.
When would I need to convert pascal (vacuum) to micron of mercury?
Vacuum-pressure conversions between Pa and µm Hg 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).
