Glossary

Hectare (ha)

A hectare is exactly 10,000 m² or one square hectometer (100 m × 100 m). Used worldwide for agricultural land, forestry, urban planning and large parcels. 1 hectare equals 0.01 km² and approximately 2.471 acres. A standard FIFA football pitch is roughly 0.7 hectares; a typical farm in Europe averages 5–50 hectares.

Acre

An acre is exactly 43,560 ft² or about 4,046.86 m² (≈ 0.4047 hectares). The unit dates from medieval England, originally defined as the land a yoke of oxen could plow in a day. Standard for US farmland, real-estate lots and conservation land. 640 acres make one square mile; a typical American suburban house lot is 0.2–0.5 acres.

Metric / SI area

In the metric system, area is reported in square meters (SI base) and its scaled units — square millimeter, square centimeter, square kilometer — plus the convenient hectare (10,000 m²) for land. Each step is exactly 100× the previous because area scales as the square of length: 1 m² = 100 dm² = 10,000 cm² = 1,000,000 mm². This squared scaling is the most common manual-conversion error.

Imperial / US Customary area

US customary and UK imperial systems use square inch, square foot, square yard, acre and square mile (144 in² = 1 ft², 9 ft² = 1 yd², 4,840 yd² = 1 acre, 640 acres = 1 mi²). The acre — historically the area a team of oxen could plow in a day — survives as the standard land-parcel unit in the US. Linked to metric by 1 ft² = 0.09290304 m² exactly.
