Why is the depth of water measured in fathoms?
The fathom is an ancient unit of length that is still used in some parts of the world, especially in the maritime industry. It is equal to six feet or two yards. The fathom is thought to have originated from the 16th century English word "fathom," meaning "the outstretched arms of a man." In the early days of sailing, sailors would use a fathom line to measure the depth of the water. The line was marked with knots at regular intervals, and the number of knots that were wet when the line was dropped into the water would indicate the depth.
The fathom is still used in some parts of the world because it is a convenient unit of measurement for shallow water. It is also used in some scientific applications, such as oceanography. The fathom is a unit of length that is based on the human body, which makes it easy to remember and use.
