What is an inch (US survey)?

The inch (US survey) is a historical surveying length unit equal to exactly 100/3937 metres, used in old U.S. land surveying and mapping.

What does a megaparsec measure?

A megaparsec is a cosmological distance unit equal to one million parsecs, often used to express distances between galaxies and on large-scale cosmic structures.

Why convert from inch (US survey) to megaparsec?

This conversion helps relate terrestrial survey measurements to cosmological distances for scientific purposes, especially when integrating legacy geodetic data with astrophysical research.
