About these units
Kilometer (km)
A kilometer is equal to one thousand meters and serves as the standard large-scale terrestrial distance unit in nearly all countries that use the metric system. It provides a convenient middle ground between the human walking scale and the geographic scale of cities, regions, and countries. Road signs, maps, geographic information systems, and national transportation networks rely heavily on kilometers to express distances succinctly and uniformly. Because kilometers integrate seamlessly into the metric system, they also appear in scientific contexts—ranging from geologic fault lengths to atmospheric layer thicknesses. In natural disasters such as earthquakes or volcanic eruptions, distances from epicenters or vents are often measured in kilometers to communicate scale effectively to the public. The kilometer's widespread use demonstrates the power of the metric system's decimal structure, offering simplicity and international standardization.
Nautical League (Int) (nl (int))
The international nautical league is defined as 3 international nautical miles, or 5,556 meters. It simplifies the expression of moderately large maritime distances by grouping nautical miles into a more manageable larger unit. Because nautical miles relate directly to Earth's geometry, the nautical league also maintains a connection to latitude and longitude. While not widely used in modern navigation—pilots and mariners typically stick to nautical miles and knots—nautical leagues still appear in older literature, historical accounts of sea voyages, and some naval traditions. They offer narrative convenience when describing long journeys without resorting to extremely large numbers. The unit highlights the tendency of sailors to create practical, scaled units that simplify communication during long-distance travel.
