Convert Electron radius (classical) to petameter

Please provide values below to convert Electron radius (classical) [r_e] to petameter [Pm], or Convert petameter to Electron radius (classical).

1 r_e = 2.8179e-30 Pm. To convert Electron radius (classical) to petameter, multiply the value by 2.8179e-30; to go the other way, divide by it (1 Pm = 3.5487e+29 r_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

1 r_e = 2.8179e-30 Pm
1 Pm = 3.5487e+29 r_e
10 r_e = 2.8179e-29 Pm
100 r_e = 2.8179e-28 Pm

How to Convert Electron Radius (Classical) to Petameter

1 r_e = 2.8179403262e-30 Pm

Example: convert 15 r_e to Pm:
15 r_e = 15 × 2.8179403262e-30 Pm = 4.2269104893e-29 Pm

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.

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.
