FAQ

What is the conversion factor from kgf/cm² to mmHg?
1 kgf/cm² equals 735.5591 mmHg. To convert, multiply the value in kilograms-force per square centimetre (stress) by 735.5591.
How do I convert 1 kgf/cm² to mmHg?
1 kgf/cm² = 735.559 mmHg. For any value, multiply by 735.5591.
How do I convert mmHg back to kgf/cm²?
Divide by the same factor — or equivalently, multiply by 0.00135951. So 1 mmHg = 0.00135951 kgf/cm².
When would I need to convert kilogram-force per square centimetre (stress) to millimetre of mercury (stress)?
Stress conversions between kgf/cm² 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).
