An are (a) is a metric unit of area, defined as 100 square meters (100 m2).
It is part of the same system as the more widely known hectare. The plural form is ares.
The hectare (ha), a much more common unit for measuring land, is derived directly from the are.
The prefix 'hecto-' means 100, so one hectare is equal to 100 ares.
Since one are is 100 square meters, a hectare is equivalent to 10,000 square meters (100 ares × 100 m2/are). This makes the hectare an ideal unit for measuring large areas, such as farms, forests, and parks.
The are was first established as part of the original French metric system in 1795. It was designed to serve as a standard base unit for measuring land, simplifying calculations required by older, traditional units.
While the hectare is more common today in agriculture and forestry, the are is still used in specific contexts, such as real estate and land registries in many countries, particularly throughout Europe.
The are serves as the foundation for other metric units of land area, making conversions straightforward. The most common related units include:
