Glossary

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.

Square foot (ft²)

A square foot equals exactly 0.09290304 m². It is the dominant unit for floor area, real-estate listings and construction in the United States and a few other countries. A typical US apartment ranges 600–1,200 ft²; a standard parking space is about 200 ft². 1 m² ≈ 10.764 ft².

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.
