Rendered to 6 significant figures.
Formula
Formula
Pa = mPa × 0.001
Multiply any value in millipascals (vacuum) by 0.001 to obtain the value in pascals (vacuum).
Worked example
Convert 1000 mPa to Pa.
- 01Start with 1000 mPa.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 Pa.
Result1000 mPa = 1 Pa

FAQ
What is the conversion factor from mPa to Pa?
1 mPa equals 0.001 Pa. To convert, multiply the value in millipascals (vacuum) by 0.001.
How do I convert 1 mPa to Pa?
1 mPa = 0.001 Pa. For any value, multiply by 0.001.
How do I convert Pa back to mPa?
Divide by the same factor — or equivalently, multiply by 1000. So 1 Pa = 1000 mPa.
When would I need to convert millipascal (vacuum) to pascal (vacuum)?
Vacuum-pressure conversions between mPa 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).
