Area Converter

About the Area Converter

An area converter transforms measurements between square metres (m²), square feet (ft²), square kilometres (km²), square miles, acres, hectares, square centimetres, square inches, and square yards — covering every scale from interior room dimensions to national land areas. Area conversion is critically important in real estate (property listings use different units worldwide), agriculture (US farms are measured in acres, European farms in hectares), construction (material purchasing uses local area units), land surveying, and environmental science. Two of the most commonly confused area units globally are acres (used in USA, UK, and some Commonwealth countries) and hectares (used in most of the world under the metric system): 1 hectare = 2.471 acres. Our converter handles all standard area units with high precision and includes quick-reference size comparisons to help contextualise unfamiliar measurements.

How It Works

Base unit: square metre (m²). Key conversion factors: 1 acre = 43,560 ft² = 4,046.86 m² = 0.404686 hectares. 1 hectare = 10,000 m² = 107,639 ft² = 2.47105 acres. 1 ft² = 0.0929 m². 1 m² = 10.7639 ft². 1 km² = 1,000,000 m² = 100 hectares = 247.105 acres = 0.3861 square miles. 1 square mile = 640 acres = 2.58999 km² = 258.999 hectares. Conversion example: a 2,000 ft² apartment = 2,000 × 0.0929 = 185.8 m². A 500-acre farm = 500 × 0.404686 = 202.3 hectares. A country of 10,000 km² = 10,000 × 100 = 1,000,000 hectares = 3,861 square miles.

Tips & Best Practices

• ✓Size references: 1 acre ≈ 4/5 of a football field (including end zones = 1.32 acres). 1 hectare ≈ 2 football fields. Average US single-family home lot: 0.20 acres = 8,712 ft² = 809 m².
• ✓Real estate: US and UK residential properties are listed in square feet; most European and Asian properties in square metres. A 1,500 ft² home = 139.4 m².
• ✓Agricultural scale: 1 hectare can produce approximately 3-6 tonnes of wheat per year in moderate climates. The world's largest farms are measured in millions of hectares.
• ✓Central Park, New York: 341 hectares = 843 acres = 3.41 km². A useful mental reference for large urban areas.
• ✓UK real estate: often still uses acres for land and square feet for buildings, while commercial property increasingly uses square metres — both units appear on UK property listings.
• ✓Land survey: the US Public Land Survey System (PLSS) divides land into 6-mile-square townships (36 square miles) containing 36 sections of 1 square mile (640 acres) each.
• ✓Rooftop solar: residential roof areas for solar typically range from 100-250 m² = 1,076-2,691 ft². Each square metre of solar panels produces approximately 150-200 W of capacity.
• ✓National comparisons: France = 551,695 km²; Texas = 696,241 km²; Australia = 7,688,287 km² = 768.8 million hectares = 1.9 billion acres.
