Kilometer / Nautical Mile Units Definition
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.
Nautical Mile
The nautical mile (symbol Ma, NMb, nm, nmi or Nqc) is a unit of measurement of length used in maritime and air navigation, equal by convention to 1,852 metersd, Although not part of the International System of Units, the nautical mile is linked to it since it is defined in relation to the meter2. Historically, it has the average value of a minute of latitude of an arc of a meridian, i.e. 1,851.85 m, which has been rounded by convention to 1,852 m3.
