What is the classical electron radius?

It is a derived length scale representing where a charge’s electrostatic self-energy equals the electron rest energy, important in particle physics and scattering calculations.

What does the ken measure?

Ken is a traditional Japanese unit of length, about 1.818 meters, used mainly in architecture for bay widths and room dimensions.

Why convert between electron radius and ken?

Converting these units helps relate microscopic physical scales to traditional architectural measurements for educational or conceptual purposes.
