Factor1 mmHg = 1.333224e-7 GPa

Converter

mmHg

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1.33322GPa

Rendered to 6 significant figures.

Formula

Formula
GPa = mmHg × 1.333224e-7

Multiply any value in millimetres of mercury (stress) by 1.333224e-7 to obtain the value in gigapascals (stress).

Worked example

Convert 1e+7 mmHg to GPa.

  1. 01Start with 1e+7 mmHg.
  2. 02Multiply by the conversion factor: 1e+7 × 1.333224e-7 = 1.33322 GPa.
Result1e+7 mmHg = 1.33322 GPa

FAQ

What is the conversion factor from mmHg to GPa?
1 mmHg equals 1.333224e-7 GPa. To convert, multiply the value in millimetres of mercury (stress) by 1.333224e-7.
How do I convert 1 mmHg to GPa?
1 mmHg = 1.33322e-7 GPa. For any value, multiply by 1.333224e-7.
How do I convert GPa back to mmHg?
Divide by the same factor — or equivalently, multiply by 7500616. So 1 GPa = 7.50062e+6 mmHg.
When would I need to convert millimetre of mercury (stress) to gigapascal (stress)?
Stress conversions between mmHg and GPa 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).
