Formula

Formula
Mpsi = kPa × 1.450377e-7

Multiply any value in kilopascals (stress) by 1.450377e-7 to obtain the value in megapounds-force per square inch (stress).

Worked example

Convert 1.00000e+6 kPa to Mpsi.

  1. 01Start with 1.00000e+6 kPa.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 1.450377e-7 = 0.145038 Mpsi.
Result1.00000e+6 kPa = 0.145038 Mpsi

FAQ

What is the conversion factor from kPa to Mpsi?
1 kPa equals 1.450377e-7 Mpsi. To convert, multiply the value in kilopascals (stress) by 1.450377e-7.
How do I convert 1 kPa to Mpsi?
1 kPa = 1.45038e-7 Mpsi. For any value, multiply by 1.450377e-7.
How do I convert Mpsi back to kPa?
Divide by the same factor — or equivalently, multiply by 6894757. So 1 Mpsi = 6.89476e+6 kPa.
When would I need to convert kilopascal (stress) to megapound-force per square inch (stress)?
Stress conversions between kPa 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).
