| From | To | Formula |
|---|---|---|
| Square Meters (m²) | Square Feet (ft²) | ft² = m² × 10.7639 |
| Square Feet (ft²) | Square Meters (m²) | m² = ft² / 10.7639 |
| Square Meters (m²) | Acres (ac) | ac = m² / 4046.86 |
| Acres (ac) | Square Meters (m²) | m² = ac × 4046.86 |
| Square Meters (m²) | Hectares (ha) | ha = m² / 10000 |
| Hectares (ha) | Square Meters (m²) | m² = ha × 10000 |
| Square Meters (m²) | Square Miles (mi²) | mi² = m² / 2,589,988 |
| Square Miles (mi²) | Square Meters (m²) | m² = mi² × 2,589,988 |
