FAQ

What is the conversion factor from GPa to kgf/mm²?
1 GPa equals 101.9716 kgf/mm². To convert, multiply the value in gigapascals (stress) by 101.9716.
How do I convert 1 GPa to kgf/mm²?
1 GPa = 101.972 kgf/mm². For any value, multiply by 101.9716.
How do I convert kgf/mm² back to GPa?
Divide by the same factor — or equivalently, multiply by 0.00980665. So 1 kgf/mm² = 0.00980665 GPa.
When would I need to convert gigapascal (stress) to kilogram-force per square millimetre (stress)?
Stress conversions between GPa and kgf/mm² 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).
