How to Convert Megameter to Electron Radius (Classical)
1 Mm = 3.54869118661751e+20 r_e
Example: convert 15 Mm to r_e:
15 Mm = 15 × 3.54869118661751e+20 r_e = 5.32303677992626e+21 r_e
Megameter to Electron Radius (Classical) Conversion Table
| megameter | Electron radius (classical) |

Megameter
A megameter is a unit of length in the metric system equal to 10^6 meters.
History/Origin
The prefix "mega-" for 10^6 was adopted by the CGPM (General Conference on Weights and Measures) in 1873.
Current Use
The megameter is sometimes used to specify the diameters of planets and the distances of satellites.
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.
