Formula

Formula
kPa = psi × 6.894757

Multiply any value in pounds-force per square inch (stress) by 6.894757 to obtain the value in kilopascals (stress).

Worked example

Convert 100 psi to kPa.

  1. 01Start with 100 psi.
  2. 02Multiply by the conversion factor: 100 × 6.894757 = 689.476 kPa.
Result100 psi = 689.476 kPa

FAQ

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