Formula
hPa = N/mm² × 10000
Multiply any value in newtons per square millimetre (stress) by 10000 to obtain the value in hectopascals (stress).
Worked example
Convert 1 N/mm² to hPa.
- 01Start with 1 N/mm².
- 02Multiply by the conversion factor: 1 × 10000 = 10000 hPa.
Result1 N/mm² = 10000 hPa

FAQ
What is the conversion factor from N/mm² to hPa?
1 N/mm² equals 10000 hPa. To convert, multiply the value in newtons per square millimetre (stress) by 10000.
How do I convert 1 N/mm² to hPa?
1 N/mm² = 10000 hPa. For any value, multiply by 10000.
How do I convert hPa back to N/mm²?
Divide by the same factor — or equivalently, multiply by 0.0001. So 1 hPa = 0.0001 N/mm².
When would I need to convert newton per square millimetre (stress) to hectopascal (stress)?
Stress conversions between N/mm² and hPa 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).
