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.
Kiloyard (kyd)
The kiloyard is equal to 1,000 yards (914.4 meters), providing a metric-like large-scale measure within the imperial system. It is occasionally used in sports, military, or surveying contexts where distances are large but must be expressed in imperial units. While uncommon in everyday practice, the kiloyard simplifies arithmetic over vast distances, especially when dealing with thousands of yards rather than dealing with long numbers of individual yards. Its usage demonstrates the adaptability of traditional systems to meet the need for larger-scale measurements without switching fully to metric units.
