FAQ

What is the conversion factor from kgf/mm² to psf?
1 kgf/mm² equals 204816.1 psf. To convert, multiply the value in kilograms-force per square millimetre by 204816.1.
How do I convert 1 kgf/mm² to psf?
1 kgf/mm² = 204816 psf. For any value, multiply by 204816.1.
How do I convert psf back to kgf/mm²?
Divide by the same factor — or equivalently, multiply by 4.882428e-6. So 1 psf = 4.88243e-6 kgf/mm².
When would I need to convert kilogram-force per square millimetre to pound-force per square foot?
Pressure conversions between kgf/mm² 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).
