What is a US survey fathom?

The US survey fathom is a non-SI unit of length equal to exactly 6 US survey feet, commonly used in nautical contexts to measure water depths and line lengths.

What does a megaparsec measure?

A megaparsec measures large cosmological distances, equal to one million parsecs, and is used to express distances between galaxies and clusters.

Why convert fathoms to megaparsecs?

This conversion is useful for relating maritime and hydrographic data to cosmological distance scales, particularly in scientific fields requiring data reconciliation across vastly different units.
