FAQ

What is the conversion factor from kgf/mm² to hPa?
1 kgf/mm² equals 98066.5 hPa. To convert, multiply the value in kilograms-force per square millimetre (stress) by 98066.5.
How do I convert 1 kgf/mm² to hPa?
1 kgf/mm² = 98066.5 hPa. For any value, multiply by 98066.5.
How do I convert hPa back to kgf/mm²?
Divide by the same factor — or equivalently, multiply by 1.019716e-5. So 1 hPa = 1.01972e-5 kgf/mm².
When would I need to convert kilogram-force per square millimetre (stress) to hectopascal (stress)?
Stress conversions between kgf/mm² and hPa 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).
