The definition of a decare is as follows:
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.
