Formula

Formula
ksi = mmHg × 1.933678e-5

Multiply any value in millimetres of mercury (stress) by 1.933678e-5 to obtain the value in kilopounds-force per square inch (stress).

Worked example

Convert 100000 mmHg to ksi.

  1. 01Start with 100000 mmHg.
  2. 02Multiply by the conversion factor: 100000 × 1.933678e-5 = 1.93368 ksi.
Result100000 mmHg = 1.93368 ksi

FAQ

What is the conversion factor from mmHg to ksi?
1 mmHg equals 1.933678e-5 ksi. To convert, multiply the value in millimetres of mercury (stress) by 1.933678e-5.
How do I convert 1 mmHg to ksi?
1 mmHg = 1.93368e-5 ksi. For any value, multiply by 1.933678e-5.
How do I convert ksi back to mmHg?
Divide by the same factor — or equivalently, multiply by 51714.93. So 1 ksi = 51714.9 mmHg.
When would I need to convert millimetre of mercury (stress) to kilopound-force per square inch (stress)?
Stress conversions between mmHg and ksi 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).
