About This Calculator
Area measures the size of a two-dimensional surface. Real estate and land are commonly measured in square feet, acres, or hectares depending on the country, while scientific and engineering contexts use square meters and square kilometers.
Formula
1 m² = 10.7639 ft²
1 acre = 4046.86 m² = 43,560 ft²
1 hectare = 10,000 m² = 2.47105 acres
Example Calculation
A room 50 feet × 30 feet — convert to square meters.
- Area in ft² = 50 × 30 = 1,500 ft²
- Area in m² = 1,500 × 0.0929 = 139.4 m²
1,500 ft² = 139.4 m²
