Units explained
Kilometer
A kilometer is a metric unit of length equal to one thousand meters. It is the standard unit for measuring road distances, geographic distances, and other large-scale measurements in metric countries.
The kilometer was defined alongside the meter in 1795 using the standard SI prefix kilo- (from Greek chilioi, "thousand"), denoting one thousand units.
Kilometers are used worldwide (except the United States and a few others) for road signage, geographic distance, athletic events, and scientific distances at planetary scale. Speed limits in most countries are given in km/h.
Adopted 1795 in France as part of the original metric system; the kilometer became the global standard for road and geographic distance through the 19th and 20th century metric adoption.
Cable
A cable is a nautical unit of length equal to one tenth of a nautical mile (exactly 185.2 m). It is used in maritime navigation for short-distance descriptions.
The cable derives from the historical length of a ship's anchor cable. Standardised at one tenth of an international nautical mile in 1929.
Cables are used in modern maritime navigation when describing short distances between vessels, anchoring depths, and harbor manoeuvres. Common in naval and yachting contexts.
Standardised at 1/10 nautical mile by the International Hydrographic Organization in 1929.

Worked examples
Example 1 — Convert 1 km to cable:
1 × 5.3995680346 = 5.3995680346 cable
Example 2 — Convert 100 km to cable:
100 × 5.3995680346 = 539.9568034557 cable
Real-world example — Endurance race distances
A 50-kilometer cycling or running race converts to a recognizable distance in cables. Endurance athletes coming from a different measurement system use this conversion to compare training plans across regions.
50 km × 5.3995680346 = 269.9784017279 cable
Real-world example — Maritime exclusion zone
A 200-kilometer exclusion zone (a common maritime boundary) converts to a different value in cables that's useful when describing the same zone in everyday land-distance units.
200 km × 5.3995680346 = 1079.9136069114 cable
Real-world example — Coastal cruise distances
A 10-kilometer coastal sailing route converts to a different value in cables — useful for cruise operators who switch between maritime, aviation, and road-distance units depending on the leg of the trip.
10 km × 5.3995680346 = 53.9956803456 cable
