What does one megaparsec represent?

One megaparsec equals one million parsecs and is used for measuring intergalactic distances in cosmology.

Why convert megaparsecs to atomic units of length?

This conversion bridges very large cosmic distances and atomic-scale measurements, useful in theoretical and computational physics.

Can this conversion be used for practical everyday measurements?

Due to the enormous scale difference, this conversion is mostly theoretical and not common in daily practical measurements.
