A mile is any of several units of distance, or, in physics terminology, of length. Today, one mile is mainly equal to about 1609 m on land and 1852 m at sea and in the air, but see below for the details. The abbreviation for mile is 'mi'. There are more specific definitions of 'mile' such as the metric mile, statute mile, nautical mile, and survey mile. On this site, we assume that if you only specify 'mile' you want the statute mile.

››Definition: Astronomical unit

The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length. It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles).

The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".
