Convert Roman actus to Electron radius (classical)
Please provide values below to convert Roman actus [actus] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to Roman actus.
1 actus = 1.2590e+16 r_e. To convert Roman actus to Electron radius (classical), multiply the value by 1.2590e+16; to go the other way, divide by it (1 r_e = 7.9426e-17 actus). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 actus = 1.2590e+16 r_e
- 1 r_e = 7.9426e-17 actus
- 10 actus = 1.2590e+17 r_e
- 100 actus = 1.2590e+18 r_e
How to Convert Roman Actus to Electron Radius (Classical)
1 actus = 1.2590302097647e+16 r_e
Example: convert 15 actus to r_e:
15 actus = 15 × 1.2590302097647e+16 r_e = 1.88854531464705e+17 r_e

Roman Actus
The Roman actus was a unit of length equal to 120 Roman feet, about 35.5 meters.
History/Origin
The actus was a standard unit of land measurement in the Roman Empire.
Current Use
The Roman actus is an obsolete unit of measurement.
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.
