About these units
Earth's Distance from Sun (AU (es))
The average distance from the Earth to the Sun is approximately 1 astronomical unit (AU) = 149,597,870.7 km. This distance forms the basis for measuring interplanetary distances within the solar system. Astronomers rely on the AU to calculate orbital periods, planetary alignments, and the intensity of solar radiation at different planets. Its precise measurement comes from radar ranging to planets, spacecraft telemetry, and observations of orbital mechanics. The AU provides a human-scaled reference for the vast distances in the solar system, bridging Earth-based intuition with astronomical scales. It is a cornerstone unit in celestial mechanics and planetary science.
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.
