Formula

Formula
dyn/cm² = mmHg × 1333.224

Multiply any value in millimetres of mercury (stress) by 1333.224 to obtain the value in dynes per square centimetre (stress).

Worked example

Convert 1 mmHg to dyn/cm².

  1. 01Start with 1 mmHg.
  2. 02Multiply by the conversion factor: 1 × 1333.224 = 1333.22 dyn/cm².
Result1 mmHg = 1333.22 dyn/cm²

FAQ

What is the conversion factor from mmHg to dyn/cm²?
1 mmHg equals 1333.224 dyn/cm². To convert, multiply the value in millimetres of mercury (stress) by 1333.224.
How do I convert 1 mmHg to dyn/cm²?
1 mmHg = 1333.22 dyn/cm². For any value, multiply by 1333.224.
How do I convert dyn/cm² back to mmHg?
Divide by the same factor — or equivalently, multiply by 0.0007500616. So 1 dyn/cm² = 0.000750062 mmHg.
When would I need to convert millimetre of mercury (stress) to dyne per square centimetre (stress)?
Stress conversions between mmHg and dyn/cm² 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).
