About Ares
An are (a) is a metric unit of area equal to 100 square meters (10 m × 10 m). Though less commonly used today, it served as an intermediate unit between square meters and hectares in the metric system. One are equals 0.01 hectares or about 119.6 yd². It is still occasionally used in some European countries for measuring medium-sized land plots, gardens, and vineyards. The dekameter-squared (dam²) is another name for the same unit.
