1 acre = 0.404686 hectares. 1 hectare = 2.47105 acres. Quick reference: 1 acre ≈ 0.4 hectares. 10 acres ≈ 4 hectares. 100 acres ≈ 40.5 hectares. 1 hectare = 10,000 m². 1 acre = 43,560 ft² = 4,047 m². Context: A football field (American) ≈ 1.32 acres ≈ 0.53 hectares. A soccer field ≈ 1.7 acres ≈ 0.7 hectares. Central Park, NYC ≈ 843 acres ≈ 341 hectares. Typical US suburban lot: 0.25 acres ≈ 0.1 hectares. The hectare is the standard unit in most countries for land area.

1 square meter = 10.7639 square feet. 1 square foot = 0.092903 square meters. Common area conversions: 100 m² = 1,076 ft² (a typical 2-bedroom apartment). 500 m² = 5,382 ft². 1,000 m² = 10,764 ft² (≈ 0.25 acres). For real estate: European listings use m², US/UK often use ft². Converting: a 2,000 sq ft US home = 185.8 m². A 100 m² European apartment = 1,076 sq ft. Quick mental conversion: m² × 10 ≈ ft² (rough approximation, actual = ×10.764). Or: ft² ÷ 10 ≈ m².

1 square kilometer = 100 hectares = 1,000,000 m². 1 hectare = 0.01 km² = 10,000 m². Relationship: 1 km² is a square that is 1 km × 1 km. A hectare is 100m × 100m (a square with 100-meter sides). For reference: Singapore = 728.6 km² = 72,860 hectares. Monaco = 2.02 km² = 202 hectares. A large farm: 500 hectares = 5 km² ≈ 1,235 acres. Countries use km² for national land areas, hectares for agricultural land and smaller regions, m² for buildings and lots.

1 square mile = 640 acres = 2.58999 km² = 258.999 hectares = 27,878,400 ft². Context: Manhattan, NYC ≈ 22.8 square miles ≈ 59 km². London (City of London) ≈ 1 square mile. A US township (land survey unit) = 36 square miles = 23,040 acres. Texas: 268,596 square miles = 695,662 km². The square mile is rarely used internationally (mostly US/UK). Most countries use km² for larger areas. UN land use statistics are reported in km².

An are (a) = 100 m² = 0.01 hectares. Named in the French metric system (1795). Its common multiple: 1 hectare (ha) = 100 ares. Today: the are is rarely used in practice — the hectare has replaced it for land measurement. However, it appears in some European property documents. History: the are was intended to be the metric alternative to the acre. The word "hectare" literally means "hundred ares" (hecto + are). Other area units in metric: square millimeter (mm²), square centimeter (cm²), square meter (m²), are, hectare, square kilometer (km²).
