Convert Electron radius (classical) to foot (US survey)
Please provide values below to convert Electron radius (classical) [r_e] to foot (US survey) [ft (US)], or Convert foot (US survey) to Electron radius (classical).
1 r_e = 9.2452e-15 ft (US). To convert Electron radius (classical) to foot (US survey), multiply the value by 9.2452e-15; to go the other way, divide by it (1 ft (US) = 1.0816e+14 r_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
Foot (Us Survey)
The U.S. survey foot was a unit of length defined as exactly 1200/3937 meters.
History/Origin
The U.S. survey foot was used for land surveying in the United States for most of the 20th century. Its use was officially phased out in 2022 to standardize with the international foot.
Current Use
The U.S. survey foot is now an obsolete unit.
