Area Converter – Convert Square Feet, Acres, Hectares and More
The area converter instantly translates between the most common area units used in real estate, construction, agriculture, and land surveying. Whether you are comparing home sizes listed in square feet, evaluating farmland in acres, or working with international measurements in hectares and square meters, this tool gives you accurate conversions in real time.
How Area Conversion Works
Area conversion uses fixed ratios between units. All area units can be expressed relative to the square meter (m²), which serves as the base SI unit:
Converted Area = Original Area × (Source Unit in m²) ÷ (Target Unit in m²)
For example, converting 2,500 square feet to square meters: 2,500 × 0.0929 = 232.3 m².
Worked Example
You are looking at a 0.75-acre lot and want to know the size in square feet and square meters:
- Square feet: 0.75 × 43,560 = 32,670 sq ft
- Square meters: 0.75 × 4,046.86 = 3,035 m²
- Hectares: 0.75 × 0.4047 = 0.304 ha
This is roughly the size of three-quarters of an American football field (including end zones).

| Square mile | mi² | 2,589,988 | 27,878,400 |
Common Use Cases
Real estate: Home sizes in the United States are listed in square feet. The median American home is about 2,300 sq ft (214 m²). When comparing properties internationally — for example, apartments in Europe listed in m² — quick conversion is essential.
Agriculture and land: Farmland in the U.S. is measured in acres. A typical small farm might be 50–100 acres. In most other countries, hectares are used. One section of land (used by the USDA and county assessors) equals 640 acres or about 259 hectares.
Construction and landscaping: Builders calculate material quantities based on area — flooring, paint, sod, and roofing are all priced per square foot or square yard. Converting between these units ensures accurate cost estimates.
Lot sizing and zoning: City zoning codes specify minimum lot sizes in square feet or acres depending on the municipality. A typical suburban lot in the U.S. ranges from 0.1 to 0.5 acres (4,356–21,780 sq ft).

Understanding Acres
The acre is the most common land measurement unit in the United States. One acre equals 43,560 square feet — roughly the size of 75% of an American football field. Historical fun fact: an acre was originally defined as the amount of land a yoke of oxen could plow in one day.
Common acre comparisons:
- 1 acre ≈ 16 tennis courts
- 1 acre ≈ 0.756 of a football field (including end zones)
- Manhattan ≈ 14,600 acres
- Average U.S. farm ≈ 445 acres (USDA 2022 data)
Frequently Asked Questions
How many square feet are in an acre?
One acre equals 43,560 square feet. This is the standard conversion used in US real estate, agriculture, and land surveying.
How do I convert square feet to square meters?
Multiply square feet by 0.0929. For example, 2,000 sq ft × 0.0929 = 185.8 m². This conversion is useful when comparing US home sizes with international listings.
What is the difference between a hectare and an acre?
A hectare is 10,000 m² (about 2.47 acres), while an acre is 4,047 m² (about 0.405 hectares). The U.S. uses acres; most other countries use hectares.
How big is a typical lot in the United States?
A typical suburban lot ranges from about 0.1 to 0.5 acres (4,356 to 21,780 square feet). Urban lots can be much smaller, while rural lots are often 1 acre or more.
What is a section of land?
A section is a unit used by the USDA and county assessors equal to 1 square mile, or 640 acres (259 hectares). It dates back to the Public Land Survey System.
