Key Formulas

Acre → Square Foot

ft² = ac × 43560

Square Foot → Acre

ac = ft² × 0.0000229568

Hectare → Acre

ac = ha × 2.47105

Acre → Hectare

ha = ac × 0.404686

Formula

ha = km² × 100

One 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.
