Formula

Formula
kgf/mm² = N/mm² × 0.1019716

Multiply any value in newtons per square millimetre (stress) by 0.1019716 to obtain the value in kilograms-force per square millimetre (stress).

Worked example

Convert 100 N/mm² to kgf/mm².

  1. 01Start with 100 N/mm².
  2. 02Multiply by the conversion factor: 100 × 0.1019716 = 10.1972 kgf/mm².
Result100 N/mm² = 10.1972 kgf/mm²

FAQ

What is the conversion factor from N/mm² to kgf/mm²?
1 N/mm² equals 0.1019716 kgf/mm². To convert, multiply the value in newtons per square millimetre (stress) by 0.1019716.
How do I convert 1 N/mm² to kgf/mm²?
1 N/mm² = 0.101972 kgf/mm². For any value, multiply by 0.1019716.
How do I convert kgf/mm² back to N/mm²?
Divide by the same factor — or equivalently, multiply by 9.80665. So 1 kgf/mm² = 9.80665 N/mm².
When would I need to convert newton per square millimetre (stress) to kilogram-force per square millimetre (stress)?
Stress conversions between N/mm² 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).
