Area Converter
Convert between square meters, square feet, acres, hectares, square kilometers, square miles, and square yards. Essential for real estate, land measurement, agriculture, and international property listings.
Conversion Formula
1 acre = 43,560 sq ft = 4,047 m² = 0.4047 hectares | 1 hectare = 10,000 m² = 2.471 acres
Area Unit Conversion Guide
Area conversion is critical in real estate (US uses square feet while most countries use square meters), agriculture (acres vs hectares), and land surveying. The two main systems differ significantly — a common source of confusion for international property buyers.
Square Meters to Square Feet
1 square meter = 10.7639 square feet. This is the most common real estate conversion. An apartment of 80 m² = 861 sq ft. A 2,000 sq ft US home = 185.8 m². To convert sq ft to sq m, divide by 10.7639 or multiply by 0.0929.
Acres to Hectares
1 acre = 0.404686 hectares. 1 hectare = 2.47105 acres. The acre is used in the US and UK; the hectare is standard internationally for agricultural land. A standard US football field is about 1.32 acres (0.53 hectares).
Square Miles vs Square Kilometers
1 square mile = 2.58999 km². This conversion is important for city area comparisons and geographical calculations. New York City covers 783.8 km² (302.6 sq mi). London covers 1,572 km² (607 sq mi).
