A hectare is a unit of measure of area that is most often used in agriculture, forestry and surveying.
One hectare (ha) is equal to ten thousand square meters. That is, 1 ha = 10,000 m2.
One hectare corresponds to a square with a side of 100 meters.
There is also 100 ares in one hectare. 1 ha = 100 ares. Hence the name “hectare” because it is a combination of the prefix “hecto-” meaning one hundred and “ar”, that is in combination – “hundred ares”.
