Formula

All conversions go through square meters as the base unit:

1 sq ft = 0.092903 sq m | 1 acre = 4046.856 sq m | 1 ha = 10,000 sq m

Example

Example: Convert 5 acres to hectares:

5 × 4046.856 / 10000 = 2.023 hectares

Frequently Asked Questions

  • One acre equals exactly 43,560 square feet. This is also equivalent to 4,046.8564 square meters, 0.40469 hectares, or 4,840 square yards. The acre originated from the area that a team of oxen could plow in one day, historically defined as a strip 1 furlong (660 feet) long by 1 chain (66 feet) wide: 660 × 66 = 43,560 sq ft. In practical terms, a US football field (including end zones) is about 1.32 acres; a typical residential lot in the US suburbs is often 0.1–0.25 acres; one acre could contain about 18 tennis courts. When buying land or property, area is described in acres in the US and UK, while most other countries use hectares or square meters.
  • One hectare equals exactly 10,000 square meters — the area of a square 100 m × 100 m. The hectare (ha) is the standard unit for measuring land and agricultural areas in most countries. It equals 2.47105 acres, 107,639 square feet, or 0.01 square kilometers. For scale: a standard soccer (football) pitch is about 0.7 hectares; a large city block is approximately 1 hectare; Central Park in New York is about 341 hectares. Farmland is typically measured in hectares internationally. The word "hectare" comes from Greek hekaton (100) and "are" — an are being 100 m². So 1 hectare = 100 ares = 10,000 m².
  • Multiply square feet by 0.09290304 to get square meters. This exact factor comes from (0.3048 m/ft)² — since 1 foot = 0.3048 m exactly, 1 sq ft = 0.3048² = 0.09290304 m². Examples: 500 sq ft = 46.45 m²; 1,000 sq ft = 92.90 m²; 2,000 sq ft = 185.81 m². To convert in the other direction (sq m to sq ft), multiply by 10.7639. A quick rule of thumb: divide square feet by 10 for a rough square-meter estimate (1,000 sq ft ≈ 100 m²), though the accurate answer is 92.9 m². This conversion is commonly needed when comparing US real estate listings (in sq ft) with European or Australian listings (in m²).
  • One square mile equals exactly 640 acres. This is because 1 mile = 5,280 feet, so 1 square mile = 5,280 × 5,280 = 27,878,400 sq ft; and 1 acre = 43,560 sq ft; therefore 27,878,400 / 43,560 = 640 acres. This relationship is embedded in the US land survey system (PLSS), where townships are 36 square miles (23,040 acres) divided into 36 sections of 1 square mile each. A square mile also equals 259.0 hectares or 2.590 km². Large ranches and wilderness areas in the western US are often described in square miles. A square mile is also called a "section" in the US Public Land Survey System.
  • Both hectares and acres measure land area, but they belong to different measurement systems. A hectare (metric) = 10,000 m² = 2.47105 acres. An acre (imperial/US customary) = 4,046.86 m² = 0.404686 hectares. So 1 hectare is about 2.47 times larger than 1 acre. The hectare is used internationally in agriculture, real estate, and land management in most countries. The acre is used primarily in the US, UK, and some Commonwealth countries. If someone describes a farm as "200 acres," that is about 81 hectares; "50 hectares" is about 124 acres. A helpful memory aid: 1 hectare ≈ 2.5 acres, or roughly "two and a half football fields" in common US parlance.
