Convert between square feet, square meters, acres, hectares, square miles, and more. Essential for real estate, agriculture, urban planning, and international property comparisons.
Most commonly needed area conversions for real estate and land
Enter any area in square feet, acres, hectares, or square meters for accurate conversions across all area units.
Open Unit Converter →Our area converter handles all major area units across metric and imperial systems:
Metric: square millimeters (mm²), square centimeters (cm²), square meters (m²), hectares (ha), square kilometers (km²)
Imperial/US: square inches (in²), square feet (ft²), square yards (yd²), acres, square miles (mi²)
Key conversion anchors:
1 sq ft = 0.092903 sq m | 1 sq m = 10.7639 sq ft
1 acre = 43,560 sq ft = 4,047 sq m = 0.4047 ha
1 hectare = 10,000 sq m = 2.471 acres
1 sq mile = 640 acres = 258.999 ha = 2.590 sq km
US real estate listings exclusively use square feet. Most of the world uses square meters. When comparing properties internationally or reading foreign listings, conversion is essential.
Common US home sizes in both units:
Studio (400–600 sq ft) = 37–56 sq m
1-bedroom (600–900 sq ft) = 56–84 sq m
2-bedroom (900–1,400 sq ft) = 84–130 sq m
3-bedroom (1,400–2,000 sq ft) = 130–186 sq m
4-bedroom (2,000–3,000 sq ft) = 186–279 sq m
Luxury home (5,000+ sq ft) = 465+ sq m
Price per area also converts: $200/sq ft = $200 ÷ 0.0929 = $2,153/sq m. European properties listed at €5,000/sq m would be about €465/sq ft.
Farming in the US uses acres; farming worldwide mostly uses hectares. Both measure large land areas but differ significantly:
1 acre ≈ a 208.7 ft × 208.7 ft square | 1 hectare = a 100 m × 100 m square (10,000 sq m)
Agricultural scale conversions:
1 acre = 0.4047 ha | 10 acres = 4.047 ha | 100 acres = 40.47 ha
1 ha = 2.471 acres | 50 ha = 123.6 acres | 100 ha = 247.1 acres
For context: a typical US family farm is 440 acres = 178 hectares. A large commercial farm in Iowa might be 2,000+ acres = 810+ hectares. In Europe, where farms are smaller, a 50-hectare farm (123 acres) is considered large.
The acre dates back to medieval England, defined as the amount of land a yoke of oxen could plow in a day. It was formalized as 4,840 square yards (43,560 square feet). The US inherited this from British colonial land systems, and with millions of property records, deeds, zoning laws, and tax records using acres and square feet, switching to metric would require enormous administrative effort.
The metric system uses square meters for rooms and apartments, hectares for agricultural land (1 ha = 10,000 sq m), and square kilometers for large geographic areas. The key relationship: 1 hectare = 10,000 sq m = the area of a square 100 meters on each side.
City planners and zoning ordinances use both systems depending on jurisdiction. Density is commonly expressed as units per acre (US) or units per hectare (metric). A city block in a typical US grid is about 2–5 acres. Manhattan's total area is 13,150 acres = 5,323 hectares = 87,130 football fields. Central Park is 840 acres = 340 hectares.
Floor Area Ratio (FAR), used in zoning, compares building floor area to land area. A FAR of 10 on a 1-acre lot allows 435,600 sq ft of building floor space — used in dense urban high-rise zones.
Sq ft to sq m: 500 sq ft = 46.5 sq m | 1,000 sq ft = 92.9 sq m | 2,000 sq ft = 185.8 sq m | 5,000 sq ft = 464.5 sq m
Sq m to sq ft: 50 sq m = 538 sq ft | 100 sq m = 1,076 sq ft | 200 sq m = 2,153 sq ft
Acres to hectares: 5 ac = 2.02 ha | 10 ac = 4.05 ha | 50 ac = 20.2 ha | 100 ac = 40.5 ha
Hectares to acres: 1 ha = 2.47 ac | 5 ha = 12.4 ac | 10 ha = 24.7 ac | 100 ha = 247 ac
Multiply sq ft by 0.0929 for sq m. Multiply sq m by 10.764 for sq ft. 2,000 sq ft = 185.8 sq m. 100 sq m = 1,076 sq ft.
1 acre = 43,560 sq ft = 4,047 sq m = 0.4047 hectares. Roughly the size of a football field (without end zones). 640 acres = 1 square mile.
1 hectare = 10,000 sq m = 2.471 acres. 1 acre = 0.4047 hectares. Hectares are the metric unit; acres are the US/UK unit. A hectare is roughly 2.5 times larger than an acre.
The average new US home is ~2,300 sq ft = 214 sq m. UK average: ~818 sq ft (76 sq m). German average: ~979 sq ft (91 sq m). US homes are significantly larger by global standards.
