Area measurements express the size of two-dimensional spaces. Different regions use different standards—the U.S. uses acres and square feet, while most of the world uses the metric system (square meters and hectares).
| Unit | Equals | Common Use |
|---|---|---|
| 1 Acre | 43,560 ft² or 4,047 m² | U.S. land plots, farms |
| 1 Hectare | 10,000 m² or 2.471 acres | International land, agriculture |
| 1 Square Meter | 10.764 ft² | Room sizes, apartments |
| 1 Square Foot | 0.0929 m² or 144 in² | Home sizes, flooring |
"Need to visualize an acre? It's roughly the size of an American football field without the end zones (about 90% of the full field). So when someone says '5-acre property,' picture 5 football fields side by side. For hectares, think of a 100m × 100m square—that's 1 hectare."

Acres: U.S. real estate, agriculture, zoning laws
Hectares: International land sales, forestry, environmental studies
Square Meters: European real estate, apartment sizes globally
Square Feet: U.S./Canadian home sizes, office space, retail
One acre equals 43,560 square feet. This is a standard U.S. land measurement. To visualize: an acre is roughly the size of an American football field (minus the end zones), which is about 208 feet × 209 feet.
Divide square meters by 10,000 to get hectares. Formula: Hectares = m² ÷ 10,000. For example: 50,000 m² = 5 hectares. The hectare is the standard metric unit for land area, commonly used worldwide except in the U.S.
An acre is a U.S. customary unit (43,560 ft² or 4,047 m²), while a hectare is a metric unit (10,000 m² or 2.471 acres). Hectares are used in most countries worldwide. One hectare is roughly 2.5 times larger than an acre. Our Area Converter makes this easy.
For rectangular land: Multiply length × width. For example, a lot that's 100 feet × 200 feet = 20,000 ft². To convert to acres: divide by 43,560 = 0.459 acres. For irregular shapes, break them into rectangles or triangles and sum the areas. Use the Area Converter above to verify.
