FAQ

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