Foot / Kilometer Units Definition
Foot
The foot is a unit of length of approximately 30 centimeters, corresponding to the length of a human foot of approximately size 45.In Antiquity, the foot was regularly divided into sixteen fingers or four palms. The Roman foot was 29.64 cm.Since the Middle Ages, the foot was also divided by twelve, which gave the inch. The foot of the King of France was 32.48 cm (size 48¾) and the Anglo-Saxon foot is 30.48 cm.
Kilometer
The kilometer (symbol km) is a unit of length, created in 1790, worth 1,000 meters1.It is the multiple of the meter most frequently used to measure terrestrial distances (for example: between cities). Kilometer points are thus defined along communication routes, which are materialized on roads by road markers.The linear kilometer is also used in the field of archives, to quantify their volume; it corresponds to the cumulative length of the shelves occupied by the documents[ref. necessary].The symbol for the prefix kilo- is the lowercase k.
