The units
The SI unit of area: a square 1 m on each side.
Used for: Floor area and property listings in most countries.
A square 1 km on each side — 1,000,000 m² or 100 hectares.
Used for: City, country and land areas.
Area factors are the squares of exact length factors, so they are exact too (an international acre is exactly 4,046.8564224 m²).
