Stress

N/cm²toN/mm²

Convert newtons per square centimetre (stress) (N/cm²) to newtons per square millimetre (stress) (N/mm²).

Factor1 N/cm² = 0.01 N/mm²

Converter

N/cm²

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

Result
1N/mm²

Rendered to 6 significant figures.

Formula

Formula
N/mm² = N/cm² × 0.01

Multiply any value in newtons per square centimetre (stress) by 0.01 to obtain the value in newtons per square millimetre (stress).

Worked example

Convert 100 N/cm² to N/mm².

  1. 01Start with 100 N/cm².
  2. 02Multiply by the conversion factor: 100 × 0.01 = 1 N/mm².
Result100 N/cm² = 1 N/mm²

FAQ

What is the conversion factor from N/cm² to N/mm²?
1 N/cm² equals 0.01 N/mm². To convert, multiply the value in newtons per square centimetre (stress) by 0.01.
How do I convert 1 N/cm² to N/mm²?
1 N/cm² = 0.01 N/mm². For any value, multiply by 0.01.
How do I convert N/mm² back to N/cm²?
Divide by the same factor — or equivalently, multiply by 100. So 1 N/mm² = 100 N/cm².
When would I need to convert newton per square centimetre (stress) to newton per square millimetre (stress)?
Stress conversions between N/cm² 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).
