Stress
kPatoGPa
Convert kilopascals (stress) (kPa) to gigapascals (stress) (GPa).
Factor1 kPa = 1e-6 GPa
Converter
kPa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
GPa
Rendered to 6 significant figures.
Formula
Formula
GPa = kPa × 1e-6
Multiply any value in kilopascals (stress) by 1e-6 to obtain the value in gigapascals (stress).
Worked example
Convert 1.00000e+6 kPa to GPa.
- 01Start with 1.00000e+6 kPa.
- 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 GPa.
Result1.00000e+6 kPa = 1 GPa

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