What is a fathom (US survey)?

It is a non-SI length unit used mainly for nautical measurements, equivalent to exactly 6 US survey feet or approximately 1.8288 meters.

What does one light year represent?

A light year is the distance light travels in a vacuum during one Julian year, about 9.4607 × 10^15 meters, commonly used in astronomy.

Why convert fathoms to light years?

Conversions help contextualize small maritime measurements relative to immense cosmic distances for educational or comparative analysis.
