GPatoN/mm²

Convert gigapascals (stress) (GPa) to newtons per square millimetre (stress) (N/mm²).

Factor1 GPa = 1000 N/mm²

Converter

GPa

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

Result
1000N/mm²

Rendered to 6 significant figures.

Formula

Formula
N/mm² = GPa × 1000

Multiply any value in gigapascals (stress) by 1000 to obtain the value in newtons per square millimetre (stress).

Worked example

Convert 1 GPa to N/mm².

  1. 01Start with 1 GPa.
  2. 02Multiply by the conversion factor: 1 × 1000 = 1000 N/mm².
Result1 GPa = 1000 N/mm²

FAQ

What is the conversion factor from GPa to N/mm²?
1 GPa equals 1000 N/mm². To convert, multiply the value in gigapascals (stress) by 1000.
How do I convert 1 GPa to N/mm²?
1 GPa = 1000 N/mm². For any value, multiply by 1000.
How do I convert N/mm² back to GPa?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 N/mm² = 0.001 GPa.
When would I need to convert gigapascal (stress) to newton per square millimetre (stress)?
Stress conversions between GPa 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).
