Rendered to 6 significant figures.
Formula
Formula
MPa = hPa × 0.0001
Multiply any value in hectopascals (stress) by 0.0001 to obtain the value in megapascals (stress).
Worked example
Convert 10000 hPa to MPa.
- 01Start with 10000 hPa.
- 02Multiply by the conversion factor: 10000 × 0.0001 = 1 MPa.
Result10000 hPa = 1 MPa

FAQ
What is the conversion factor from hPa to MPa?
1 hPa equals 0.0001 MPa. To convert, multiply the value in hectopascals (stress) by 0.0001.
How do I convert 1 hPa to MPa?
1 hPa = 0.0001 MPa. For any value, multiply by 0.0001.
How do I convert MPa back to hPa?
Divide by the same factor — or equivalently, multiply by 10000. So 1 MPa = 10000 hPa.
When would I need to convert hectopascal (stress) to megapascal (stress)?
Stress conversions between hPa 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).
