Mile (US Survey)

The US survey mile is a unit of length used in land surveying in the United States. It is defined as exactly 5,280 survey feet, with one survey foot equal to 1200/3937 meters (approximately 0.3048006096 meters). This makes the US survey mile equal to about 1,609.3472 meters, slightly longer than the international (statute) mile, which is exactly 1,609.344 meters.

The US survey mile was established to maintain consistency with older land measurement systems based on the Mendenhall Order of 1893. It was commonly used in mapping, legal land descriptions, and public land surveys.

Although the difference between the survey and statute mile is very small (about 3.2 millimeters), it can be significant over large distances. As of 2023, the U.S. has officially retired the survey foot (and survey mile) for most applications, favoring the international foot and mile to standardize measurements.

Furlong

A furlong is a traditional unit of distance used primarily in agriculture and horse racing. It is equal to 220 yards, 660 feet, or 1/8 of a mile (approximately 201.168 meters).

The word "furlong" comes from the Old English words furh (furrow) and lang (long), originally referring to the length of a furrow in a 10-acre field. It was historically used in England to measure field lengths for plowing.

In modern times, the furlong is rarely used outside of horse racing, where race distances are still often given in furlongs, especially in the United Kingdom and the United States.
