Please provide values below to convert exameter [Em] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to exameter.
How to Convert Exameter to Electron Radius (Classical)
1 Em = 3.54869118661751e+32 r_e
Example: convert 15 Em to r_e:
15 Em = 15 × 3.54869118661751e+32 r_e = 5.32303677992626e+33 r_e
Exameter to Electron Radius (Classical) Conversion Table
| exameter | Electron radius (classical) |
|---|
Exameter
An exameter is a unit of length in the metric system equal to 10^18 meters.
History/Origin
The prefix "exa-" for 10^18 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The exameter is used in astronomy to measure the vast distances between galaxies.
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.
