What does the classical electron radius represent?

It is a derived length scale representing the distance at which the classical electrostatic self-energy of a charge equals the electron rest energy, commonly used as a characteristic scattering length.

Why convert electron radius to gigameters?

To relate very small electromagnetic scattering scales to very large units of astronomical distance, facilitating comparison across vastly different physical scales.

Is the electron radius the actual size of the electron?

No, it is a theoretical length scale, not a physical size, often used in calculations related to scattering and classical electromagnetic theory.
