Units explained
Furlong
A furlong is an Imperial unit of length equal to 660 feet, or exactly one eighth of a mile (about 201.17 m). It is the longest unit in the traditional English farm-and-survey system.
The furlong derives from Old English furh (furrow) + lang (long) — originally the length of a furrow in a typical medieval English open field. Standardised at 660 feet (= 10 chains = 220 yards = 1/8 mile) in medieval times.
Furlongs are the standard distance unit in horse racing (e.g., 'The race is 8 furlongs'), historical English farming and surveying, and occasional poetic or rhetorical usage. Modern racing courses worldwide list distances in furlongs.
Medieval English farming origin; standardised at 660 feet; remains the official distance unit in flat-racing thoroughbred horse races worldwide.
Cubit
The UK cubit is an Imperial unit of length equal to 18 inches (457.2 mm). It represents the historical distance from the elbow to the tip of the middle finger.
Cubits derive from ancient body-measure traditions found in Mesopotamia, Egypt, and the eastern Mediterranean. The English customary cubit was standardised at 18 inches in medieval times.
UK cubits are rare in modern commerce but appear in historical English texts, biblical references, and historical reconstructions. Different cultures used cubits of different lengths.
Ancient origin; standardised at 18 inches in English customary practice; became exact via the 1959 International Yard and Pound Agreement.
