One fathom is equal to 6 feet.
A fathom is a unit of length equal to six feet or 1.8288 meters. It is used primarily in nautical contexts, such as when measuring the depth of water or the length of a ship. The word “fathom” comes from the Old English word “faethm,” which means “embrace.” This is because a fathom was originally defined as the distance between the outstretched arms of a man.
The fathom is still used today in some nautical contexts, but it is not an official unit of measurement in any country. It is, however, a recognized unit of measurement by the International Organization for Standardization (ISO).
