Stress
PatoN/mm²
Convert pascals (stress) (Pa) to newtons per square millimetre (stress) (N/mm²).
Factor1 Pa = 1e-6 N/mm²
Converter
Pa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
N/mm²
Rendered to 6 significant figures.
Formula
Formula
N/mm² = Pa × 1e-6
Multiply any value in pascals (stress) by 1e-6 to obtain the value in newtons per square millimetre (stress).
Worked example
Convert 1.00000e+6 Pa to N/mm².
- 01Start with 1.00000e+6 Pa.
- 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 N/mm².
Result1.00000e+6 Pa = 1 N/mm²

FAQ
What is the conversion factor from Pa to N/mm²?
1 Pa equals 1e-6 N/mm². To convert, multiply the value in pascals (stress) by 1e-6.
How do I convert 1 Pa to N/mm²?
1 Pa = 1e-6 N/mm². For any value, multiply by 1e-6.
How do I convert N/mm² back to Pa?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 N/mm² = 1.00000e+6 Pa.
When would I need to convert pascal (stress) to newton per square millimetre (stress)?
Stress conversions between Pa and N/mm² 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).
