FAQ
What is the conversion factor from ksi to N/cm²?
1 ksi equals 689.4757 N/cm². To convert, multiply the value in kilopounds-force per square inch (stress) by 689.4757.
How do I convert 1 ksi to N/cm²?
1 ksi = 689.476 N/cm². For any value, multiply by 689.4757.
How do I convert N/cm² back to ksi?
Divide by the same factor — or equivalently, multiply by 0.001450377. So 1 N/cm² = 0.00145038 ksi.
When would I need to convert kilopound-force per square inch (stress) to newton per square centimetre (stress)?
Stress conversions between ksi and N/cm² are routine in mechanics-of-materials work: yield, ultimate and allowable-stress specification, Young's-modulus tables and structural-design code calculations. MPa and N/mm² dominate ISO and European datasheets, psi and ksi dominate US structural codes, and kgf/cm² and kgf/mm² appear in legacy JIS and heavy-engineering documentation. Stress is the same physical dimension as pressure but a different engineering quantity — this category is mechanics-of-materials, not process pressure.
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).
