what is a hectare

A hectare is a non-SI metric unit of area equal to a square with 100-meter sides, which is equivalent to 10,000 square meters or 2.471 acres. It is primarily used in the measurement of land and is the legal unit of measure in many countries for land ownership, planning, and management, including law (land deeds), agriculture, forestry, and town planning throughout the European Union and Australia. One hectare is larger than an acre of land, and there are 100 hectares in one square kilometer
