The square kilometer (km2) is a unit of measurement of area. One square kilometer is equal to the area of a square whose sides measure one kilometer.
Hectare
hectare, unit of area in the metric system equal to 100 ares, or 10,000 square meters, and the equivalent of 2.471 acres in the British imperial system and the customary measurement of the United States. The term is derived from the Latin area and hect, an irregular contraction of the Greek word percent. Although the are is the primary metric unit of land measurement, the hectare is more commonly used in practice. The hectare is, by definition, equal to one djerib in Turkey, one jerib in Iran, one gong qing in mainland China, one manzana in Argentina and one bunder in the Netherlands.
