About these units
Furlong (fur)
A furlong, equal to 10 chains or 660 feet, originated as the distance a team of oxen could plow before needing rest. Its name derives from "furrow-long," indicating the length of a typical plowed furrow in medieval agriculture. This agricultural basis linked the furlong to the acre: a rectangle one furlong long and one chain wide equaled one acre in area. Today, the furlong is most notably used in horse racing, where race distances are often measured in furlongs rather than miles. This tradition reflects both the unit's historical importance and its suitability for describing moderate distances. While archaic in most contexts, the furlong remains a culturally iconic measure that connects modern sports to medieval agricultural practices.
Inch (US Survey) (in (US))
The US Survey Inch is derived from the US survey foot, making it exactly 1/12 of the US survey foot (~2.540006 cm). It is used in precise surveying applications where small differences can accumulate over large distances. Historically, it ensured consistency in cadastral maps, railroad engineering, and construction projects, especially when reconciling legacy measurements with modern geodetic data. Though seldom used outside surveying, the US survey inch highlights the need for consistency and precision in civil engineering and mapping applications.
