Rendered to 6 significant figures.
Formula
Formula
MPa = GPa × 1000
Multiply any value in gigapascals (stress) by 1000 to obtain the value in megapascals (stress).
Worked example
Convert 1 GPa to MPa.
- 01Start with 1 GPa.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 MPa.
Result1 GPa = 1000 MPa

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