Furlong

What is a 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.

Origin of the furlong

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.

Where it is used

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.

When and where it was developed

Medieval English farming origin; standardised at 660 feet; remains the official distance unit in flat-racing thoroughbred horse races worldwide.

Caliber

What is a 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.

Origin of the caliber

The caliber as a length unit derives from the inch by hundredth subdivision. Standardised through the 1959 International Yard and Pound Agreement.

Where it is used

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.

When and where it was developed

Length-unit usage standardised through the 1959 International Yard and Pound Agreement; the bore-diameter usage long predates this.
