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.
Caliber
In length-measurement context, a caliber is a unit equal to one hundredth of an inch (2.54×10⁻⁴ m). The same word also refers to a firearm's bore diameter; in that context the value depends on the specific cartridge.
The caliber as a length unit derives from the inch by hundredth subdivision. Standardised through the 1959 International Yard and Pound Agreement.
Calibers appear in ballistics literature (alongside the more common usage as bore diameter), historical small-arms specifications, and a few precision-engineering contexts. Often confused with the cartridge-naming caliber, which is a different concept.
Length-unit usage standardised through the 1959 International Yard and Pound Agreement; the bore-diameter usage long predates this.
