GPatokPa
Convert gigapascals (stress) (GPa) to kilopascals (stress) (kPa).
Factor1 GPa = 1000000 kPa
Converter
GPa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
kPa
Rendered to 6 significant figures.
Formula
Formula
kPa = GPa × 1000000
Multiply any value in gigapascals (stress) by 1000000 to obtain the value in kilopascals (stress).
Worked example
Convert 1 GPa to kPa.
- 01Start with 1 GPa.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 kPa.
Result1 GPa = 1.00000e+6 kPa

FAQ
What is the conversion factor from GPa to kPa?
1 GPa equals 1000000 kPa. To convert, multiply the value in gigapascals (stress) by 1000000.
How do I convert 1 GPa to kPa?
1 GPa = 1.00000e+6 kPa. For any value, multiply by 1000000.
How do I convert kPa back to GPa?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 kPa = 1e-6 GPa.
When would I need to convert gigapascal (stress) to kilopascal (stress)?
Stress conversions between GPa and kPa 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).
