## ››Definition: Square astronomical unit

A square astronomical unit is defined as the area of a square with sides one astronomical unit in length.

The definition of a astronomical unit is as follows:

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".

## ››Definition: Hectare

A hectare (symbol ha) is a metric unit of surface area, equal to 100 ares (the name is a contraction of the SI prefix hecto + are). It is a non-SI unit currently accepted (although discouraged) for use with the SI. Its use is widespread in agriculture where it is more practical than either square metres or square kilometres, typical fields being a few hectares in size.
