Inch / Kilometer Units Definition
Inch
The inch (symbol: ″ (double prime) or po in French-speaking Canada) is a unit of length dating back to the Middle Ages.Its dimensional value has varied over time, across regions and across countries.Since 1959, following an English compromise, the English inch — also called the “international technical inch” — has been exactly 2.54 cm, or one twelfth of a foot or one thirty-sixth (1⁄36) of a yard. For historical reasons, other definitions of the inch are still in force in certain areas.
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.
