Furlong (US Survey)

The furlong (US survey) is a traditional unit of distance used in U.S. land surveying, defined as 1/8 of a U.S. survey mile, or exactly 660 U.S. survey feet. Since one U.S. survey foot equals approximately 0.3048006096 meters, the US survey furlong is about 201.1684 meters long.

While the difference between the US survey furlong and the international (standard) furlong is extremely small (just a few micrometers), it was significant in precise land measurements, particularly in legal and cadastral surveying contexts.

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.
