Definition: The hectare is a large metric land unit. It equals 10,000 m², so a square plot 100 meters on each side has an area of one hectare.

Current use: Ha is common in agricultural reports, conservation areas, forestry, vineyards, land registries, planning documents, and international comparisons of property or habitat size.
