FAQ

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