›› 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: Decare

The decare is a unit for the measurement of area, generally used for land area. One decare (from deka, 10 and are) is the same as 10 ares, which is the same as 1000 square metres. Though its base unit, the are, was defined by older forms of the metric system, it is not part of the modern metric system, the International System (SI). It is accepted, but not encouraged, for use with the SI.

The decare is not widely used, except in Norway and many of the formerly Ottoman countries; it corresponds roughly to the Byzantine stremma and the Ottoman donum, and exactly to the metric stremma and donum.
