How this area converter works
Area is measured in two main systems: the metric system (square meters, hectares and square kilometers) and the imperial / US customary system (square inches, square feet, square yards, acres and square miles). To convert accurately between them, this tool turns whatever you type into a single base unit — square meters — and then expresses that base value in every other unit. Converting through a base avoids the rounding errors that creep in when you chain conversions one after another.
The exact factors used are: 1 ft² = 0.09290304 m², 1 yd² = 0.83612736 m², 1 in² = 0.00064516 m², 1 mi² = 2,589,988.110336 m², 1 acre = 4,046.8564224 m², 1 hectare = 10,000 m² and 1 km² = 1,000,000 m². The most-searched pairings — square feet to square meters, acres to hectares and acres to square feet — are highlighted so you can read them at a glance.
Common conversions
| From | Equals |
|---|---|
| 1 square meter (m²) | 10.7639 square feet (ft²) |
| 1 square foot (ft²) | 0.092903 square meters (m²) |
| 1 acre | 4,046.86 square meters / 43,560 sq ft |
| 1 hectare (ha) | 2.4711 acres / 10,000 m² |
| 1 square mile (mi²) | 640 acres / 2.59 km² |
Reference note: factors follow the international foot (0.3048 m, exact) and the international acre. Results are rounded for readability, so very small differences in the last decimal are normal.
