Quick Answer & Understanding Your Result
An Area Converter translates surface area measurements between Metric (Square Meters, Hectares, Square Kilometers) and Imperial (Square Feet, Acres, Square Yards, Square Miles) conforming to ISO 80000-3 standards.
Core Land & Surface Area Equivalents
- 1 Square Meter (m²): Exactly 10.7639104 square feet (sq ft).
- 1 Hectare (ha): Exactly 10,000 m² ≈ 2.4710538 acres.
- 1 Acre (ac): 43,560 sq ft ≈ 4,046.8564 m² ≈ 0.4046856 ha.
- 1 Square Kilometer (km²): 1,000,000 m² = 100 hectares ≈ 0.3861 sq mi.
- 1 Square Mile (sq mi): 640 acres ≈ 2.589988 km².
Standard Conversion Formulas
- m² to Square Feet: sq ft = m² × 10.7639.
- Square Feet to m²: m² = sq ft / 10.7639.
- Acres to Hectares: ha = acres × 0.4046856.
