Formula

Formula
N/cm² = psf × 0.004788026

Multiply any value in pounds-force per square foot (stress) by 0.004788026 to obtain the value in newtons per square centimetre (stress).

Worked example

Convert 1000 psf to N/cm².

  1. 01Start with 1000 psf.
  2. 02Multiply by the conversion factor: 1000 × 0.004788026 = 4.78803 N/cm².
Result1000 psf = 4.78803 N/cm²

FAQ

What is the conversion factor from psf to N/cm²?
1 psf equals 0.004788026 N/cm². To convert, multiply the value in pounds-force per square foot (stress) by 0.004788026.
How do I convert 1 psf to N/cm²?
1 psf = 0.00478803 N/cm². For any value, multiply by 0.004788026.
How do I convert N/cm² back to psf?
Divide by the same factor — or equivalently, multiply by 208.8543. So 1 N/cm² = 208.854 psf.
When would I need to convert pound-force per square foot (stress) to newton per square centimetre (stress)?
Stress conversions between psf and N/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).
