Accepts numbers or expressions, e.g. 150 + 14.7
Result
mmHg
Rendered to 6 significant figures.
Formula
Formula
mmHg = Pa × 0.007500616
Multiply any value in pascals (stress) by 0.007500616 to obtain the value in millimetres of mercury (stress).
Worked example
Convert 1000 Pa to mmHg.
- 01Start with 1000 Pa.
- 02Multiply by the conversion factor: 1000 × 0.007500616 = 7.50062 mmHg.
Result1000 Pa = 7.50062 mmHg

FAQ
What is the conversion factor from Pa to mmHg?
1 Pa equals 0.007500616 mmHg. To convert, multiply the value in pascals (stress) by 0.007500616.
How do I convert 1 Pa to mmHg?
1 Pa = 0.00750062 mmHg. For any value, multiply by 0.007500616.
How do I convert mmHg back to Pa?
Divide by the same factor — or equivalently, multiply by 133.3224. So 1 mmHg = 133.322 Pa.
When would I need to convert pascal (stress) to millimetre of mercury (stress)?
Stress conversions between Pa and mmHg are routine in mechanics-of-materials work: yield, ultimate and allowable-stress specification, Young's-modulus tables and structural-design code calculations. MPa and N/mm² dominate ISO and European datasheets, psi and ksi dominate US structural codes, and kgf/cm² and kgf/mm² appear in legacy JIS and heavy-engineering documentation. Stress is the same physical dimension as pressure but a different engineering quantity — this category is mechanics-of-materials, not process pressure.
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).
