Please provide values below to convert megaparsec [Mpc] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to megaparsec.
How to Convert Megaparsec to Electron Radius (Classical)
1 Mpc = 1.09501168374316e+37 r_e
Example: convert 15 Mpc to r_e:
15 Mpc = 15 × 1.09501168374316e+37 r_e = 1.64251752561473e+38 r_e
Megaparsec to Electron Radius (Classical) Conversion Table
| megaparsec | Electron radius (classical) |
|---|
Megaparsec
A megaparsec is a unit of distance used in astronomy, equal to one million parsecs.
History/Origin
The parsec was first coined by British astronomer Herbert Hall Turner in 1913. The megaparsec came into use as astronomical distance measurements extended to other galaxies.
Current Use
The megaparsec is used to measure the distances between neighboring galaxies and galaxy clusters.
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.
