Convert between square meters, square kilometers, square feet, square yards, acres, hectares, and square miles. Useful for property size, land area, and floor plans.
Quick reference
- 1 sq ft = 0.092903 m²
- 1 m² = 10.7639 sq ft
- 1 acre = 4,046.86 m² = 43,560 sq ft
- 1 hectare = 10,000 m² = 2.47105 acres
- 1 sq mile = 2.58999 km² = 640 acres
Property listings are the most common reason people need an area converter — square feet versus square meters, or acres versus hectares for land. The reference table below covers the conversions that come up most in real estate and farming.
How to convert area units
Area units are squares of length units, so the conversion factor is squared too. One foot is 0.3048 m, so one square foot is 0.3048 × 0.3048 = 0.0929 m². A common mistake is multiplying square feet by 3.28 (the length factor) instead of dividing by 10.764.
Example: a 1,500 sq ft home is 1,500 × 0.092903 = 139.35 m².
