How to Convert Electron Radius (Classical) to Chain (Us Survey)
1 r_e = 1.40078675053518e-16 ch (US)
Example: convert 15 r_e to ch (US):
15 r_e = 15 × 1.40078675053518e-16 ch (US) = 2.10118012580277e-15 ch (US)

Electron Radius (Classical)
The classical electron radius is a quantity with the dimension of length, approximately 2.82 x 10⁻¹⁵ meters.
History/Origin
The classical electron radius is a concept from classical physics that attempts to model the electron as a spherical shell of charge. It is not considered the actual size of an electron.
Current Use
The classical electron radius appears in the Thomson scattering cross-section and is a useful length scale in atomic and high-energy physics.
Chain (Us Survey)
A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.
History/Origin
The U.S. survey chain is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey chain was used for land surveying in the United States.
