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.
Centiinch
A centiinch is an Imperial unit of length equal to one hundredth of an inch (2.54×10⁻⁴ m). It is functionally identical to the caliber as a length unit but appears in different industrial contexts.
Derived from the inch via the metric-style prefix centi- (Latin centum, hundred). Standardised through the 1959 International Yard and Pound Agreement.
Centiinches occasionally appear in older engineering specifications and US-localised metric-pseudo notation. Most contemporary use prefers thousandths (mils) for sub-inch precision.
Standardised through the 1959 International Yard and Pound Agreement; rarely used in modern practice.
