FAQ

What is the conversion factor from hPa to psf?
1 hPa equals 2.088543 psf. To convert, multiply the value in hectopascals (stress) by 2.088543.
How do I convert 1 hPa to psf?
1 hPa = 2.08854 psf. For any value, multiply by 2.088543.
How do I convert psf back to hPa?
Divide by the same factor — or equivalently, multiply by 0.4788026. So 1 psf = 0.478803 hPa.
When would I need to convert hectopascal (stress) to pound-force per square foot (stress)?
Stress conversions between hPa 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).
