About Hectare (ha)
A metric unit of area equal to 10,000 square meters (100 m × 100 m), or about 2.47 acres. Hectares are the international standard for agricultural land, forestry, national parks, and land-use statistics outside the US — European farmers, Canadian forestry, Australian ranches, and FAO global statistics all use hectares. A hectare is a convenient human-scale unit between the square meter (too small for farms) and the square kilometer (too large for individual parcels).
About Square Mile (mi²)
An imperial unit of area equal to a square with 1-mile sides (approximately 2.59 km² or 640 acres). Square miles are the customary unit in the US for county sizes, national parks, metro-area footprints, wildfire burn areas, and watershed reporting. Alaska is 665,384 mi²; Yellowstone National Park is 3,468 mi²; Manhattan is 22.8 mi². Geographic conversions between square miles and square kilometers are among the most frequent area conversions for US news consumers reading international reports.
