FAQ

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