A "kiloyard" is not a commonly used unit of measurement, and it is not part of the International System of Units (SI). In everyday conversation and most scientific contexts, the yard is used as a unit of length in some countries, primarily the United States and the United Kingdom. One yard is equal to 3 feet or 36 inches.
The prefix "kilo-" typically denotes a factor of 1,000. So, a "kiloyard" would theoretically be 1,000 yards. However, this term is not standard in any established system of measurement and is unlikely to be encountered in practical use. If you need to express a length of 1,000 yards, it's more common to simply say "1,000 yards" or "one thousand yards" rather than using the term "kiloyard."
A fathom is a unit of length used to measure the depth of water or the depth of objects underwater. In the international nautical mile system, one fathom is equal to exactly 1.8288 meters or approximately 6 feet. However, in the United States, the customary value for a fathom is often rounded to 6 feet.
Fathoms are commonly used in navigation, maritime activities, and underwater exploration to measure the depth of bodies of water, the draft of ships, and the depth of diving. Sailors, fishermen, and divers often use this unit to assess water depths.
