What does an attometer measure?

An attometer is an SI unit of length equal to one quintillionth of a metre, typically used in subnuclear and high-energy physics to describe extremely small distances.

What is a megaparsec used for?

A megaparsec is a unit for length equal to one million parsecs and is commonly used to express vast intergalactic and cosmological distances.

Why convert attometers to megaparsecs?

Converting attometers to megaparsecs helps relate very small particle physics scales to the enormous distances encountered in cosmology, providing a way to compare vastly different length scales.
