What does one megaparsec represent?

One megaparsec is a length unit equal to one million parsecs, useful for measuring intergalactic distances and cosmological scales.

What is an astronomical unit?

An astronomical unit is the distance defined as exactly 149,597,870,700 metres, approximately the average distance from Earth to the Sun.

Why convert megaparsecs to astronomical units?

Converting megaparsecs to astronomical units helps relate large-scale cosmic distances to Solar System scales for comparison and analysis.
