Please provide values below to convert rod [rd] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to rod.
How to Convert Rod to Electron Radius (Classical)
1 rd = 1.78470777157368e+15 r_e
Example: convert 15 rd to r_e:
15 rd = 15 × 1.78470777157368e+15 r_e = 2.67706165736051e+16 r_e
Rod to Electron Radius (Classical) Conversion Table
| rod | Electron radius (classical) |

Rod
A rod, also known as a perch or pole, is a unit of length equal to 16.5 feet, or 5.5 yards.
History/Origin
The rod has been used as a unit of measurement in England since at least the 13th century. It was a convenient length for measuring land.
Current Use
The rod is now an archaic unit of measurement, though it may still be encountered in old land deeds.
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.
