What does the classical electron radius represent?

It is a derived length scale indicating the distance at which the electrostatic self-energy of an electron equals its rest energy, serving as a characteristic scattering length rather than a physical size.

Why convert from electron radius to parsec?

Converting helps relate very small electromagnetic scattering lengths to very large astronomical distances to aid in interdisciplinary physics and astronomy research.

Can this conversion be used for practical measurements?

The conversion is mostly conceptual since the classical electron radius is theoretical and the scales differ immensely.

Tips & Best Practices

Use this tool for conceptual understanding of scale differences between particle physics and astronomy.
Be aware that the classical electron radius is a theoretical value, not a physical size.
Note that results produce extremely small numbers due to the vast difference in scales.

Limitations

The classical electron radius does not represent a literal electron size but a derived theoretical scale.
Conversion to parsecs is mainly conceptual since the length scales differ by many orders of magnitude.
Calculated values may be susceptible to floating-point precision limitations in computations.
