Factor1 Pa = 1e-9 GPa
Converter
Pa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
GPa
Rendered to 6 significant figures.
Formula
Formula
GPa = Pa × 1e-9
Multiply any value in pascals (stress) by 1e-9 to obtain the value in gigapascals (stress).
Worked example
Convert 1e+9 Pa to GPa.
- 01Start with 1e+9 Pa.
- 02Multiply by the conversion factor: 1e+9 × 1e-9 = 1 GPa.
Result1e+9 Pa = 1 GPa

FAQ
What is the conversion factor from Pa to GPa?
1 Pa equals 1e-9 GPa. To convert, multiply the value in pascals (stress) by 1e-9.
How do I convert 1 Pa to GPa?
1 Pa = 1e-9 GPa. For any value, multiply by 1e-9.
How do I convert GPa back to Pa?
Divide by the same factor — or equivalently, multiply by 1e+9. So 1 GPa = 1e+9 Pa.
When would I need to convert pascal (stress) to gigapascal (stress)?
Stress conversions between Pa 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).
