What is a kiloparsec used for?

A kiloparsec measures large interstellar and galactic distances such as separations within a galaxy or sizes of galactic structures.

When should I use petameters instead of kiloparsecs?

Petameters are suitable for expressing very large distances with SI prefixes, especially for scales larger than the Solar System but smaller than typical interstellar distances.

How do I convert from kiloparsecs to petameters?

Multiply the number of kiloparsecs by 30856.7758128 to get the equivalent length in petameters.
