Area Converter
Convert between sq ft, sq m, acres, hectares, and more.
Area measurements underpin real estate, agriculture, flooring, and urban planning. The same fundamental challenge that affects length conversions — metric vs. imperial — applies here, but the discrepancies are squared (a factor-of-10 difference in length becomes factor-of-100 in area). Understanding area units is essential when comparing land prices across countries, ordering flooring materials, or reading agricultural yield data.

Standards Note: Acres and Hectares Have Fixed Benchmarks
NIST Handbook 44 lists 1 hectare as exactly 10,000 square meters and 1 acre as 0.40468564224 hectare, which makes land-area cross-checks much easier.

Square Feet, Square Meters, and Real Estate
The United States measures home and apartment sizes in square feet (sq ft). Most other countries use square meters (m²). One square meter equals approximately 10.76 square feet, so a 1,000 sq ft apartment is about 93 m². European apartments listed at 70 m² are roughly 753 sq ft — a modest one-bedroom by US standards. When browsing international real estate listings, mentally dividing square feet by 10 gives a rough square meter estimate.
Acres, Hectares, and Land
For large land areas, the US uses acres while most of the world uses hectares. One hectare equals 10,000 m² or about 2.47 acres. One acre is approximately 4,047 m² or 0.4 hectares. Crop yield data published by international organizations like the FAO uses hectares, so understanding this conversion is important for interpreting agricultural statistics. A football field (including end zones) is about 0.54 hectares or 1.32 acres.
| Unit | Equivalent |
|---|---|
| 1 sq in | 6.452 cm² |
| 1 sq ft | 0.0929 m² |
| 1 sq yd | 0.836 m² |
| 1 acre | 4,047 m² / 0.405 ha |
| 1 sq mile | 2.59 km² / 259 ha |
| 1 hectare | 10,000 m² / 2.47 acres |
Practical Tips: Flooring and Tiling
When ordering flooring or tiles, US suppliers typically sell by the square foot while European suppliers sell by the square meter. Always add 10–15% to your calculated area to account for waste from cutting and pattern matching. To convert your room dimensions: if a room is 12 ft × 15 ft, that's 180 sq ft or approximately 16.7 m². Tile boxes often list coverage in both units on the label — check both to avoid ordering the wrong quantity.
