Exact Conversion Factors
Area units square the length conversions, so the inch-to-centimeter factor of 2.54 becomes 6.4516 per square inch, and the foot becomes exactly 0.09290304 square meters. The acre is the one US land buyers should memorize: 43,560 square feet, 4,046.86 square meters, just over four tenths of a hectare. The hectare is the clean metric unit: exactly 10,000 square meters, 2.47105 acres. For quick mental math, 1 acre ≈ 4,047 m², 1 ha ≈ 2.47 acres, 1 ft² ≈ 0.093 m², and 1 m² ≈ 10.76 ft².
Worked Example
A listing says the lot is half an acre and you think in square meters. 0.5 x 4,046.8564224 = 2,023.428 m². A farm of 160 acres (a quarter section) in hectares: 160 x 0.404685642 = 64.7497 ha. A 2,000 sq ft house in square meters: 2,000 x 0.09290304 = 185.806 m². And going the other way, a 100 m² apartment is 100 x 10.7639104 = 1,076.391 ft². Punch each into the converter and check the all-unit table.
Where This Comes Up
Real estate is the big one: US listings talk acres and square feet while international listings talk hectares and square meters, and buyers crossing between them need both. Renters compare apartment sizes the same way. Builders and contractors convert floor plans and material coverage, since paint, flooring, and roofing are all priced by the square foot or square meter. Farmers and ranchers live in acres and square miles. Gardeners scale seed and fertilizer rates from square feet to square meters. Even sports help: an American football field (without end zones) is about 1.32 acres, a handy mental picture.
Frequently Asked Questions
How many square feet are in an acre?
43,560 square feet in 1 acre. That comes from the old definition: one chain (66 feet) by one furlong (660 feet). In metric that is 4,046.8564 square meters, or 0.404686 hectares.

How many acres are in a square mile?
640 acres in 1 square mile. That is why US land parcels so often come in round numbers like 40, 80, or 160 acres: they are quarters, eighths, and sixteenths of a square-mile section. A quarter section is 160 acres.
How do I convert square feet to square meters?
Multiply square feet by 0.09290304. So 1,000 sq ft equals 92.903 m2, and 2,500 sq ft equals 232.258 m2. For a quick estimate, multiply by 0.093, or divide by 10.76.
What is the difference between an acre and a hectare?
Both measure land, but the acre is imperial (4,046.86 m2) and the hectare is metric (10,000 m2). The hectare is about 2.47 times larger than the acre. US real estate listings use acres and square feet; most of the rest of the world uses hectares and square meters.
