FAQ

What is the conversion factor from psf to kgf/m²?
1 psf equals 4.882428 kgf/m². To convert, multiply the value in pounds-force per square foot by 4.882428.
How do I convert 1 psf to kgf/m²?
1 psf = 4.88243 kgf/m². For any value, multiply by 4.882428.
How do I convert kgf/m² back to psf?
Divide by the same factor — or equivalently, multiply by 0.2048161. So 1 kgf/m² = 0.204816 psf.
When would I need to convert pound-force per square foot to kilogram-force per square metre?
Pressure conversions between psf and kgf/m² 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).
