Please provide values below to convert Planck length [l_P] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to Planck length.
How to Convert Planck Length to Electron Radius (Classical)
1 l_P = 5.73558987382648e-21 r_e
Example: convert 15 l_P to r_e:
15 l_P = 15 × 5.73558987382648e-21 r_e = 8.60338481073972e-20 r_e
Planck Length to Electron Radius (Classical) Conversion Table
| Planck length | Electron radius (classical) |
|---|
Planck Length
The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.
History/Origin
The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.
Current Use
The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
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.
