Factor1 Pa = 0.0001450377 psi
Converter
Pa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
psi
Rendered to 6 significant figures.
Formula
Formula
psi = Pa × 0.0001450377
Multiply any value in pascals (stress) by 0.0001450377 to obtain the value in pounds-force per square inch (stress).
Worked example
Convert 100000 Pa to psi.
- 01Start with 100000 Pa.
- 02Multiply by the conversion factor: 100000 × 0.0001450377 = 14.5038 psi.
Result100000 Pa = 14.5038 psi

FAQ
What is the conversion factor from Pa to psi?
1 Pa equals 0.0001450377 psi. To convert, multiply the value in pascals (stress) by 0.0001450377.
How do I convert 1 Pa to psi?
1 Pa = 0.000145038 psi. For any value, multiply by 0.0001450377.
How do I convert psi back to Pa?
Divide by the same factor — or equivalently, multiply by 6894.757. So 1 psi = 6894.76 Pa.
When would I need to convert pascal (stress) to pound-force per square inch (stress)?
Stress conversions between Pa and psi 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).
