Mile
A mile is a unit of length commonly used in the United States and the United Kingdom to measure long distances. One mile equals 5,280 feet or about 1.609 kilometers. Miles are often used to measure distances between cities, in running races like the mile run, or for driving distances shown on road signs. The abbreviation for mile is "mi". Although many countries use the metric system with kilometers, miles remain popular in some places for everyday distance measurements and travel.
Chain
A chain is a unit of length traditionally used in land surveying. The most common version is the Gunter’s chain, which equals 66 feet or 22 yards, approximately 20.1168 meters.
The chain was introduced by English clergyman Edmund Gunter in the 17th century to simplify land measurement. One chain consists of 100 links, each 0.66 feet long. It became a standard unit in British and American land surveying and was instrumental in defining land areas, especially in the U.S. Public Land Survey System.
Key Conversions:
1 chain = 66 feet
1 chain = 22 yards
1 chain ≈ 20.1168 meters
10 chains = 1 furlong
80 chains = 1 mile
Though now largely replaced by metric units and modern surveying tools, the chain still appears in older land deeds, maps, and rural property descriptions.
