What is a femtometer used for?

A femtometer is a unit of length used to measure extremely small distances such as atomic nuclei sizes and interaction distances in nuclear physics.

What does the classical electron radius represent?

It is a theoretical length scale related to the electron’s electrostatic energy and scattering properties, not its actual physical size.

How do I convert femtometers to electron radius (classical)?

Multiply the femtometer value by 0.3548690439 to obtain its equivalent in classical electron radius units.
