15 r_e = 15 × 1.7434998352364e+20 l_P = 2.61524975285459e+21 l_P

Electron Radius (Classical) to Planck Length Conversion Table

Electron radius (classical)	Planck length

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.

Planck Length

The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.

History/Origin

The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.

Current Use

The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
