What is Astronomical Units?
Astronomical Units (au) is a unit of length. An astronomical unit (au) is defined as exactly 149,597,870.7 kilometers. It represents the average distance from Earth to the Sun and is used as a standard measure for distances within the solar system [cgpm-resolutions]. The astronomical unit was formally defined by the International Astronomical Union in 2012 to replace earlier approximations and improve measurement precision in celestial mechanics [cgpm-resolutions]. The au is the standard unit of length in astronomy for expressing distances between planets and other solar system bodies. It is used globally by space agencies such as NASA and ESA [nist-cuu].
What is Feet?
Feet (ft) is a unit of length. A foot is a unit of length defined as exactly 0.3048 meters. It consists of 12 inches and is commonly used in the United States, Liberia, and Myanmar for height, distance, and construction measurements. The foot remains part of the imperial and U.S. customary systems standardized internationally [nist-si-guide]. The foot originated from various historical measurements based on the length of a human foot. It was standardized by the international yard and pound agreement in 1959, fixing the foot at exactly 0.3048 meters [nist-si-guide]. Feet are widely used in the U.S. for building construction, aviation altitudes, and everyday height measurements. Despite global metrication, feet remain common in real estate, sports, and engineering within certain countries [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: astronomical unit, au unit, astronomic unit, astronomical unites, foot, feets, fet, feet's, feets. All of these refer to the Astronomical Units to Feet conversion.
