FAQ

What is the conversion factor from kgf/mm² to N/mm²?
1 kgf/mm² equals 9.80665 N/mm². To convert, multiply the value in kilograms-force per square millimetre by 9.80665.
How do I convert 1 kgf/mm² to N/mm²?
1 kgf/mm² = 9.80665 N/mm². For any value, multiply by 9.80665.
How do I convert N/mm² back to kgf/mm²?
Divide by the same factor — or equivalently, multiply by 0.1019716. So 1 N/mm² = 0.101972 kgf/mm².
When would I need to convert kilogram-force per square millimetre to newton per square millimetre?
Pressure conversions between kgf/mm² and N/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).
