About Hectare (ha)
A metric unit of area equal to exactly 10,000 m² (= 100 m × 100 m square = 2.47105 acres). The hectare is the international working unit for: agricultural land per FAO Statistics Division (typical European family farm 30-100 ha; Canadian prairie wheat operation 500-5,000 ha; Australian station/ranch 50,000-1,000,000 ha; Brazilian soy farm 1,000-50,000 ha; world's largest cattle ranch 9.1 million ha — Anna Creek Station, Australia); forestry and protected-area management (the Amazon biome covers ~550 million ha; Russian forests ~815 million ha; FSC and PEFC forest-certification reporting); national parks worldwide except US (Banff National Park 664,100 ha; Serengeti 1,476,300 ha; Galápagos National Park 798,500 ha); FAO World Programme for the Census of Agriculture per UNFAO methodology — all global crop-yield, livestock-density, and food-security statistics reported per ha. Hectares are also used for vineyard sizes (Bordeaux AOC 110,000 ha total; Napa Valley AVA 18,000 ha), olive groves, palm-oil plantations, and rice-paddy area in Southeast Asia. A convenient human-scale unit between m² (too small for farms) and km² (too large for individual parcels). Convert ha to acres by multiplying by 2.471; to km² by dividing by 100.
About Square Kilometer (km²)
A metric unit of area equal to exactly 1,000,000 m² (a square with 1-kilometer sides). Square kilometers are the default unit for geographic scale: country sizes per CIA World Factbook + UN Statistics Division (Russia 17,098,242 km² largest; Vatican City 0.49 km² smallest; USA 9,833,517 km²; China 9,596,961 km²; Brazil 8,515,767 km²; Australia 7,692,024 km²; Canada 9,984,670 km²; France 643,801 km²; UK 243,610 km²; Germany 357,022 km²; Japan 377,975 km²); city/metro footprints (Manhattan 59 km²; NYC 783.8 km²; London Greater 1,572 km²; Tokyo 23 special wards 627 km²; Mexico City 1,485 km²); forest and agricultural land per FAO FRA reporting; deforestation tracking per MapBiomas, Global Forest Watch (Amazon biome ~5.5 million km²); urban heat-island and wildfire burn-area reporting in news (2018 Camp Fire 620 km²; 2020 Australian bushfires 186,000 km²); lake and watershed areas (Lake Superior 82,100 km²; Mississippi River basin 3,202,200 km²); satellite-imagery scene footprints (Landsat 8 scene ~32,000 km²). km² is the preferred unit in most international geographic statistics, climate models, and macro-scale GIS analysis.
