Formula
psi = kPa × 0.1450377
Multiply any value in kilopascals by 0.1450377 to obtain the value in pounds-force per square inch.
Worked example
Convert 700 kPa to psi.
- 01Start with 700 kPa.
- 02Multiply by the conversion factor: 700 × 0.1450377 = 101.526 psi.
Result700 kPa = 101.526 psi

FAQ
What is the conversion factor from kPa to psi?
1 kPa equals 0.1450377 psi. To convert, multiply the value in kilopascals 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 to pound-force per square inch?
Pressure conversions between kPa and psi are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
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).
