Formula

Formula
Mpsi = kgf/mm² × 0.001422334

Multiply any value in kilograms-force per square millimetre (stress) by 0.001422334 to obtain the value in megapounds-force per square inch (stress).

Worked example

Convert 1000 kgf/mm² to Mpsi.

  1. 01Start with 1000 kgf/mm².
  2. 02Multiply by the conversion factor: 1000 × 0.001422334 = 1.42233 Mpsi.
Result1000 kgf/mm² = 1.42233 Mpsi

FAQ

What is the conversion factor from kgf/mm² to Mpsi?
1 kgf/mm² equals 0.001422334 Mpsi. To convert, multiply the value in kilograms-force per square millimetre (stress) by 0.001422334.
How do I convert 1 kgf/mm² to Mpsi?
1 kgf/mm² = 0.00142233 Mpsi. For any value, multiply by 0.001422334.
How do I convert Mpsi back to kgf/mm²?
Divide by the same factor — or equivalently, multiply by 703.0696. So 1 Mpsi = 703.07 kgf/mm².
When would I need to convert kilogram-force per square millimetre (stress) to megapound-force per square inch (stress)?
Stress conversions between kgf/mm² and Mpsi 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).
