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. This unit is fundamental in agriculture, forestry, environmental conservation, and international land measurement standards.
About Square Megameters
A square megameter (Mm²) equals the area of a square with sides of one million meters - 10¹² m², or one trillion square meters. At this scale we describe major geographic and planetary regions. The entire land surface of Earth is about 149 Mm², the Indian Ocean covers roughly 70 Mm², and the Sahara Desert spans approximately 9.2 Mm². Square megameters provide a convenient scale for comparing continent-sized areas without resorting to hundreds of millions of square kilometers.
