About Hectares
A hectare (ha) is a metric unit of area equal to 10,000 m² (100 m × 100 m). It is the primary unit for measuring agricultural land, forests, and large properties worldwide outside the United States. One hectare equals 2.471 acres. A FIFA-regulation football pitch is about 0.7 ha, and Vatican City is 44 ha.
