What Is This Tool?

This converter transforms values from barn to square mil, helping users translate extremely small nuclear and particle physics area measurements into imperial-based units used in electronics and manufacturing.

How to Use This Tool?

  • Enter the value in barn [b] you want to convert
  • Select barn as the input unit and square mil [mil²] as the output unit
  • Click the convert button to see the equivalent area in square mil
  • Review the result, often displayed in scientific notation due to small values

Key Features

  • Converts between barn and square mil units of area accurately
  • Supports extremely small value conversions relevant to physics and precision engineering
  • Browser-based tool requiring no installation
  • User-friendly interface for quick input and results

Examples

  • Convert 2 barn [b] to 3.1000062e-19 square mil [mil²]
  • Convert 0.5 barn [b] to 7.7500155e-20 square mil [mil²]

Common Use Cases

  • Reporting nuclear reaction and neutron-capture cross sections in scientific data tables
  • Expressing particle collision cross sections in accelerator experiments
  • Specifying PCB copper trace areas and pad sizes in electronics using imperial units
  • Measuring cross-sectional areas of flat conductors and metal foils in electrical engineering
  • Quantifying very small surface areas in thin-film coatings and precision manufacturing

Tips & Best Practices

Frequently Asked Questions

What is a barn used for?
A barn measures extremely small area values primarily in nuclear and particle physics, such as cross sections in nuclear reactions and particle collisions.

Where is square mil commonly applied?
Square mil is used in precision electronics and manufacturing, especially for PCB copper traces and measuring small planar areas in electrical engineering.

Can I convert circular mil with this tool?
No, this converter only supports conversion between barn and square mil, and does not handle circular mil units.

Key Terminology

Barn [b]
A unit of area equal to 1×10⁻²⁸ square metres, used mainly in nuclear and particle physics for cross-sectional areas.
Square mil [mil²]
