What is the classical electron radius?

It is a derived length scale defined via fundamental constants representing a characteristic scattering length, not the actual size of an electron.

What is the US survey chain?

A traditional unit of length used historically in US land surveying, equal to 66 US survey feet and subdivided into 100 links.

Why convert electron radius values to survey chains?

To express extremely small atomic scale lengths in terms of a historic land measurement unit for educational or cross-disciplinary comparison.

Examples

1 Electron radius (classical) equals 1.4007870457121e-16 chain (US survey).
10 Electron radius (classical) equals 1.4007870457121e-15 chain (US survey).

Common Use Cases

Expressing atomic-scale lengths using a traditional land survey unit for educational comparisons.
Bridging physical constants from particle physics with historic surveying data.
Understanding scale differences between quantum distances and land measurement units.
Converting historic survey measurements for cross-disciplinary analysis.

Tips & Best Practices

Ensure input values represent lengths in Electron radius (classical) units before conversion.
Use this conversion mainly for theoretical, educational, or comparative purposes.
Consider the historical context of the US survey chain when applying results.
Do not rely on this conversion for practical land measurements.

Limitations

Electron radius (classical) is a theoretical length scale and not a physical size of the electron.
Chain (US survey) is a large unit not suited for tiny quantum-scale values; conversions result in extremely small decimals.
The classical electron radius and conversion constants involve approximations.
US survey chain use is largely historical and replaced by metric units in modern mapping.
