Key Formulas
Acre → Square Foot
ft² = ac × 43560Square Foot → Acre
ac = ft² × 0.0000229568Hectare → Acre
ac = ha × 2.47105Acre → Hectare
ha = ac × 0.404686Formula
ha = km² × 100One kilometer equals 100 hectares — this is by definition since 1 km² = 1,000,000 m² and 1 ha = 10,000 m². Land managers, farmers, and foresters in metric countries think in hectares rather than km² because it gives more manageable numbers for individual properties. A 10 km² estate is 1000 ha, not 10 million m².
