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 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 to kilopascal?
Pressure conversions between psi and kPa 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).
