About these units
Yard (yd)
A yard equals 3 feet or 36 inches and serves as a mid-range imperial length unit. Historically, one definition of the yard was the distance from the tip of King Henry I's nose to his thumb when his arm was extended, though later attempts standardized the measure. Today, yards appear in sports (football, golf), textiles (fabric sales), and landscaping. In construction and engineering, the yard is sometimes used for larger distances where a foot would be too small a unit and a mile too large. Because it divides cleanly into both inches and feet, the yard plays a structural role in the imperial measurement system. It bridges the gap between human-scale and large-scale distances.
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.
