FAQ

What is the conversion factor from psi to kgf/mm²?
1 psi equals 0.0007030696 kgf/mm². To convert, multiply the value in pounds-force per square inch by 0.0007030696.
How do I convert 1 psi to kgf/mm²?
1 psi = 0.00070307 kgf/mm². For any value, multiply by 0.0007030696.
How do I convert kgf/mm² back to psi?
Divide by the same factor — or equivalently, multiply by 1422.334. So 1 kgf/mm² = 1422.33 psi.
When would I need to convert pound-force per square inch to kilogram-force per square millimetre?
Pressure conversions between psi and kgf/mm² 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).
