Units explained
Foot
A foot is an Imperial and US customary unit of length equal to 12 inches or exactly 0.3048 meters. It is the most commonly used unit of length in everyday measurement in the United States.
The foot's origin is literally the length of a human foot, used as a measurement standard since antiquity. The English foot was standardized at various points in history; the modern international foot (0.3048 m exactly) was fixed by the 1959 International Yard and Pound Agreement.
Feet are used in the US for body height, building dimensions, room sizes, road sign clearances, aviation altitude (feet above sea level), and most everyday distance estimation. The UK uses feet informally for height despite officially being metric.
Used since antiquity; standardized to 0.3048 m exactly by the International Yard and Pound Agreement of 1959. Aviation worldwide uses feet for altitude despite metric adoption elsewhere.
Finger
A finger is an Imperial unit of length equal to 4.5 inches (114.3 mm). It is one of the historical English cloth-measure units.
The finger derives from English cloth-trade tradition, where it was used as a small measure for ribbons and small fabric pieces. Standardised at 4.5 inches through English customary practice.
Fingers are rare in modern use; they appear primarily in historical English textile records and bartending (where 'a finger of whisky' is an informal usage roughly 1 inch, not 4.5).
Medieval English cloth-trade origin; standardised at 4.5 inches; the value became exact via the 1959 International Yard and Pound Agreement.
