FAQ

What is the conversion factor from N/mm² to ksi?
1 N/mm² equals 0.1450377 ksi. To convert, multiply the value in newtons per square millimetre by 0.1450377.
How do I convert 1 N/mm² to ksi?
1 N/mm² = 0.145038 ksi. For any value, multiply by 0.1450377.
How do I convert ksi back to N/mm²?
Divide by the same factor — or equivalently, multiply by 6.894757. So 1 ksi = 6.89476 N/mm².
When would I need to convert newton per square millimetre to kilopound-force per square inch?
Pressure conversions between N/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).
