Formula

Formula
Pa = µm Hg × 0.1333224

Multiply any value in microns of mercury by 0.1333224 to obtain the value in pascals (vacuum).

Worked example

Convert 1000 µm Hg to Pa.

  1. 01Start with 1000 µm Hg.
  2. 02Multiply by the conversion factor: 1000 × 0.1333224 = 133.322 Pa.
Result1000 µm Hg = 133.322 Pa

FAQ

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