FAQ

What is the conversion factor from kgf/mm² to ksi?
1 kgf/mm² equals 1.422334 ksi. To convert, multiply the value in kilograms-force per square millimetre by 1.422334.
How do I convert 1 kgf/mm² to ksi?
1 kgf/mm² = 1.42233 ksi. For any value, multiply by 1.422334.
How do I convert ksi back to kgf/mm²?
Divide by the same factor — or equivalently, multiply by 0.7030696. So 1 ksi = 0.70307 kgf/mm².
When would I need to convert kilogram-force per square millimetre to kilopound-force per square inch?
Pressure conversions between kgf/mm² and ksi 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).
