What is a megaparsec used for?

A megaparsec is used to express large-scale distances such as those between galaxies and in cosmological measurements.

Why convert megaparsecs to attometers?

This conversion helps relate vast cosmological distances to extremely small lengths relevant in subnuclear physics, facilitating scale comparisons.

Is the attometer commonly used outside high-energy physics?

No, the attometer is primarily used for describing extremely small distances in particle and nuclear physics.
