What unit of measurement is represented by "fathom"?

The term "fathom" refers specifically to a unit of length that is commonly used to measure the depth of water, with one fathom equivalent to 6 feet. This measurement is particularly relevant in nautical contexts, where understanding water depth is crucial for navigation, anchoring, and ensuring the safety of vessels. Fathoms are traditionally employed in maritime practices to provide a clearer understanding of underwater distances, distinguishing them from other measurement units that may not align with aquatic applications. By using fathoms, mariners can communicate more effectively and ensure a safer journey across varying water depths.
