Formula

Formula
GPa = ksi × 0.006894757

Multiply any value in kilopounds-force per square inch (stress) by 0.006894757 to obtain the value in gigapascals (stress).

Worked example

Convert 1000 ksi to GPa.

  1. 01Start with 1000 ksi.
  2. 02Multiply by the conversion factor: 1000 × 0.006894757 = 6.89476 GPa.
Result1000 ksi = 6.89476 GPa

FAQ

What is the conversion factor from ksi to GPa?
1 ksi equals 0.006894757 GPa. To convert, multiply the value in kilopounds-force per square inch (stress) by 0.006894757.
How do I convert 1 ksi to GPa?
1 ksi = 0.00689476 GPa. For any value, multiply by 0.006894757.
How do I convert GPa back to ksi?
Divide by the same factor — or equivalently, multiply by 145.0377. So 1 GPa = 145.038 ksi.
When would I need to convert kilopound-force per square inch (stress) to gigapascal (stress)?
Stress conversions between ksi and GPa 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).
