Are
From Wikipedia, the free encyclopedia
- This article is about the unit of area. For other uses, see Are (disambiguation).
An are (symbol a) is a unit of area, equal to 100 square meters (10 m × 10 m), used for measuring land area. It was defined by older forms of the metric system, but is not part of the modern metric system, the International System (SI). It is accepted, but not encouraged, for use with the SI.
It is commonly used in many countries—in particular, in French-, Portuguese, Polish- and German-speaking countries—to measure real estate; elsewhere, the square meter is used. The are is sometimes used in combination with the centiare, e.g. "10 ares 12 centiares" = 1012 m². Larger land areas are generally measured in hectares. The decare is occasionally encountered. Other prefixes for multiples and submultiples of the are are not in common use.
