FAQ

What is the conversion factor from kPa to psf?
1 kPa equals 20.88543 psf. To convert, multiply the value in kilopascals (stress) by 20.88543.
How do I convert 1 kPa to psf?
1 kPa = 20.8854 psf. For any value, multiply by 20.88543.
How do I convert psf back to kPa?
Divide by the same factor — or equivalently, multiply by 0.04788026. So 1 psf = 0.0478803 kPa.
When would I need to convert kilopascal (stress) to pound-force per square foot (stress)?
Stress conversions between kPa 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).
