FAQ
What is the conversion factor from kPa to psf?
1 kPa equals 20.88543 psf. To convert, multiply the value in kilopascals by 20.88543.
How do I convert 1 kPa to psf?
1 kPa = 20.8854 psf. For any value, multiply by 20.88543.
How do I convert psf back to kPa?
Divide by the same factor — or equivalently, multiply by 0.04788026. So 1 psf = 0.0478803 kPa.
When would I need to convert kilopascal to pound-force per square foot?
Pressure conversions between kPa and psf 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).
