From square metres to acres
Area units are squared lengths, so their conversion factors are the length factors squared. One hectare is 10,000 square metres, or about 2.47 acres. An acre is 43,560 square feet, and a square mile holds 640 acres. Countries that use metric units usually quote land in square metres and hectares, while the United States and the United Kingdom still use acres and square feet.

Worked examples and a common mistake
A 1,200 ft² apartment is about 111.5 m², a 100 m² house is about 1,076 ft², and a 2-acre lot is about 0.8094 hectares.
A common mistake is to reuse the length factor. One metre is about 3.28 feet, but one square metre is about 10.76 square feet, because both sides of the square change. Always convert area with area units.
