What does 1 Megaparsec represent?

1 Megaparsec is a unit of length equal to one million parsecs, a distance often used to measure intergalactic and cosmological scales.

What is the classical electron radius?

The classical electron radius is a derived length scale representing a characteristic scattering length related to the electron's electrostatic self-energy.

Why convert between megaparsec and classical electron radius?

Converting these units helps relate large cosmological distances to fundamental particle physics scales, supporting interdisciplinary research and normalization.
