FAQ

What is the conversion factor from psf to dyn/cm²?
1 psf equals 478.8026 dyn/cm². To convert, multiply the value in pounds-force per square foot (stress) by 478.8026.
How do I convert 1 psf to dyn/cm²?
1 psf = 478.803 dyn/cm². For any value, multiply by 478.8026.
How do I convert dyn/cm² back to psf?
Divide by the same factor — or equivalently, multiply by 0.002088543. So 1 dyn/cm² = 0.00208854 psf.
When would I need to convert pound-force per square foot (stress) to dyne per square centimetre (stress)?
Stress conversions between psf and dyn/cm² 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).
