What is the electron radius (classical)?

It is a derived length scale representing the distance where classical electrostatic self-energy equals the electron rest energy, used mainly in scattering calculations.

What does the fermi unit measure?

The fermi is a non-SI length unit equal to one femtometre, commonly used to express distances on the scale of atomic nuclei and nucleons.

Why convert electron radius to fermi units?

Converting to fermi helps express atomic-scale scattering lengths in a unit commonly used in nuclear and particle physics, easing comparisons.

Tips & Best Practices

Remember the classical electron radius is a theoretical length, not a physical size of an electron
Use fermi units primarily for distances at the nuclear scale to maintain meaningful interpretations
Apply conversions carefully in scattering-related physics problems for clear unit consistency
Cross-check conversion outputs when incorporating them into scientific computations or reports

Limitations

The classical electron radius is a conceptual scattering length, not the actual electron size
Fermi units are suited for nuclear-scale measurements and are less applicable to larger atomic or molecular lengths
