bartoN/mm²

Convert bar (bar) to newtons per square millimetre (N/mm²).

Factor1 bar = 0.1 N/mm²

Converter

bar

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

Result
1N/mm²

Rendered to 6 significant figures.

Formula

Formula
N/mm² = bar × 0.1

Multiply any value in bar by 0.1 to obtain the value in newtons per square millimetre.

Worked example

Convert 10 bar to N/mm².

  1. 01Start with 10 bar.
  2. 02Multiply by the conversion factor: 10 × 0.1 = 1 N/mm².
Result10 bar = 1 N/mm²

FAQ

What is the conversion factor from bar to N/mm²?
1 bar equals 0.1 N/mm². To convert, multiply the value in bar by 0.1.
How do I convert 1 bar to N/mm²?
1 bar = 0.1 N/mm². For any value, multiply by 0.1.
How do I convert N/mm² back to bar?
Divide by the same factor — or equivalently, multiply by 10. So 1 N/mm² = 10 bar.
When would I need to convert bar to newton per square millimetre?
Pressure conversions between bar and N/mm² are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
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).
