Why convert kilometers to megaparsecs?

To translate everyday or regional distance measurements into the cosmological distance scales used in astrophysics and astronomy.

What does one megaparsec represent?

One megaparsec equals one million parsecs, a distance scale used for measuring vast intergalactic distances.

Is this conversion used for everyday measurements?

No, it is mainly used in scientific and cosmological contexts rather than daily practical applications.
