Please provide values below to convert petameter [Pm] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to petameter.
How to Convert Petameter to Electron Radius (Classical)
1 Pm = 3.54869118661751e+29 r_e
Example: convert 15 Pm to r_e:
15 Pm = 15 × 3.54869118661751e+29 r_e = 5.32303677992626e+30 r_e
Petameter to Electron Radius (Classical) Conversion Table
| petameter | Electron radius (classical) |

Petameter
A petameter is a unit of length in the metric system equal to 10^15 meters.
History/Origin
The prefix "peta-" for 10^15 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The petameter is used for measuring distances on a galactic scale, such as the size of the Milky Way galaxy.
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.
