What is the classical electron radius used for?

It serves as a fundamental physical length scale in particle and radiation physics, important for calculations like the Thomson scattering cross section and normalizing electromagnetic interactions.

Why use fingerbreadth as a unit of length?

Fingerbreadth is an informal, non-standard unit based on the width of an adult finger, often used for quick, rough measurements in daily life, such as tailoring or clinical exams.

Can I use this conversion for precise measurements?

No, due to the highly variable and informal nature of the fingerbreadth, this conversion is mostly useful for illustrative or educational comparisons rather than exact measurements.
