Stress

N/mm²toPa

Convert newtons per square millimetre (stress) (N/mm²) to pascals (stress) (Pa).

Factor1 N/mm² = 1000000 Pa

Converter

N/mm²

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1.00000e+6Pa

Rendered to 6 significant figures.

Formula

Formula
Pa = N/mm² × 1000000

Multiply any value in newtons per square millimetre (stress) by 1000000 to obtain the value in pascals (stress).

Worked example

Convert 1 N/mm² to Pa.

  1. 01Start with 1 N/mm².
  2. 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 Pa.
Result1 N/mm² = 1.00000e+6 Pa

FAQ

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