FAQ

What is the conversion factor from hPa to ksi?
1 hPa equals 1.450377e-5 ksi. To convert, multiply the value in hectopascals (stress) by 1.450377e-5.
How do I convert 1 hPa to ksi?
1 hPa = 1.45038e-5 ksi. For any value, multiply by 1.450377e-5.
How do I convert ksi back to hPa?
Divide by the same factor — or equivalently, multiply by 68947.57. So 1 ksi = 68947.6 hPa.
When would I need to convert hectopascal (stress) to kilopound-force per square inch (stress)?
Stress conversions between hPa and ksi 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).
