What is a vara castellana?

A vara castellana is a historic Spanish unit of length, commonly about 0.8359 metres, used mainly in the 18th and 19th centuries.

What is a megaparsec (Mpc)?

A megaparsec is a unit used in astronomy equal to one million parsecs, approximately 3.0857 × 10^22 metres, used to measure immense cosmic distances.

Why convert from vara castellana to megaparsec?

This conversion helps illustrate the vast difference between historical geographic units and astronomical distances, useful in interdisciplinary academic scenarios.
