FAQ

What is the conversion factor from MPa to psf?
1 MPa equals 20885.43 psf. To convert, multiply the value in megapascals (stress) by 20885.43.
How do I convert 1 MPa to psf?
1 MPa = 20885.4 psf. For any value, multiply by 20885.43.
How do I convert psf back to MPa?
Divide by the same factor — or equivalently, multiply by 4.788026e-5. So 1 psf = 4.78803e-5 MPa.
When would I need to convert megapascal (stress) to pound-force per square foot (stress)?
Stress conversions between MPa and psf 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).
