Convert fermi to Electron radius (classical)
Enter a value below to convert fermi [F, f] to Electron radius (classical) [r_e]. Reverse conversion: Convert Electron radius (classical) to fermi.
1 F, f = 0.354869118662 r_e. To convert fermi to Electron radius (classical), multiply the value by 0.354869118662; to go the other way, divide by it (1 r_e = 2.8179403262 F, f). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Fermi: Definition and Use
A fermi is a unit of length equal to a femtometer, which is 10⁻¹⁵ meters.
History/Origin
The fermi is named after the Italian-American physicist Enrico Fermi. It was a popular unit in nuclear physics.
Current Use
The femtometer is the officially recognized SI unit, but the fermi is still used informally in nuclear and particle physics.
Electron Radius (Classical): Definition and Use
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.
