Stress
MPatoGPa
Convert megapascals (stress) (MPa) to gigapascals (stress) (GPa).
Factor1 MPa = 0.001 GPa
Converter
MPa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
GPa
Rendered to 6 significant figures.
Formula
Formula
GPa = MPa × 0.001
Multiply any value in megapascals (stress) by 0.001 to obtain the value in gigapascals (stress).
Worked example
Convert 1000 MPa to GPa.
- 01Start with 1000 MPa.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 GPa.
Result1000 MPa = 1 GPa

FAQ
What is the conversion factor from MPa to GPa?
1 MPa equals 0.001 GPa. To convert, multiply the value in megapascals (stress) by 0.001.
How do I convert 1 MPa to GPa?
1 MPa = 0.001 GPa. For any value, multiply by 0.001.
How do I convert GPa back to MPa?
Divide by the same factor — or equivalently, multiply by 1000. So 1 GPa = 1000 MPa.
When would I need to convert megapascal (stress) to gigapascal (stress)?
Stress conversions between MPa 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).
