Formula

Formula
mmHg = MPa × 7500.616

Multiply any value in megapascals (stress) by 7500.616 to obtain the value in millimetres of mercury (stress).

Worked example

Convert 1 MPa to mmHg.

  1. 01Start with 1 MPa.
  2. 02Multiply by the conversion factor: 1 × 7500.616 = 7500.62 mmHg.
Result1 MPa = 7500.62 mmHg

FAQ

What is the conversion factor from MPa to mmHg?
1 MPa equals 7500.616 mmHg. To convert, multiply the value in megapascals (stress) by 7500.616.
How do I convert 1 MPa to mmHg?
1 MPa = 7500.62 mmHg. For any value, multiply by 7500.616.
How do I convert mmHg back to MPa?
Divide by the same factor — or equivalently, multiply by 0.0001333224. So 1 mmHg = 0.000133322 MPa.
When would I need to convert megapascal (stress) to millimetre of mercury (stress)?
Stress conversions between MPa 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).
