Formula

Formula
N/cm² = mmHg × 0.01333224

Multiply any value in millimetres of mercury (stress) by 0.01333224 to obtain the value in newtons per square centimetre (stress).

Worked example

Convert 100 mmHg to N/cm².

  1. 01Start with 100 mmHg.
  2. 02Multiply by the conversion factor: 100 × 0.01333224 = 1.33322 N/cm².
Result100 mmHg = 1.33322 N/cm²

FAQ

What is the conversion factor from mmHg to N/cm²?
1 mmHg equals 0.01333224 N/cm². To convert, multiply the value in millimetres of mercury (stress) by 0.01333224.
How do I convert 1 mmHg to N/cm²?
1 mmHg = 0.0133322 N/cm². For any value, multiply by 0.01333224.
How do I convert N/cm² back to mmHg?
Divide by the same factor — or equivalently, multiply by 75.00616. So 1 N/cm² = 75.0062 mmHg.
When would I need to convert millimetre of mercury (stress) to newton per square centimetre (stress)?
Stress conversions between mmHg and N/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).
