Factor1 kPa = 0.1450377 psi

Converter

kPa

Accepts numbers or expressions, e.g. 150 + 14.7

Result
14.5038psi

Rendered to 6 significant figures.

Formula

Formula
psi = kPa × 0.1450377

Multiply any value in kilopascals (stress) by 0.1450377 to obtain the value in pounds-force per square inch (stress).

Worked example

Convert 100 kPa to psi.

  1. 01Start with 100 kPa.
  2. 02Multiply by the conversion factor: 100 × 0.1450377 = 14.5038 psi.
Result100 kPa = 14.5038 psi

FAQ

What is the conversion factor from kPa to psi?
1 kPa equals 0.1450377 psi. To convert, multiply the value in kilopascals (stress) by 0.1450377.
How do I convert 1 kPa to psi?
1 kPa = 0.145038 psi. For any value, multiply by 0.1450377.
How do I convert psi back to kPa?
Divide by the same factor — or equivalently, multiply by 6.894757. So 1 psi = 6.89476 kPa.
When would I need to convert kilopascal (stress) to pound-force per square inch (stress)?
Stress conversions between kPa 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).
