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 by definition. This is one of the cleanest area conversions — since 1 km² = 1,000,000 m² and 1 ha = 10,000 m², then 1 km² = 100 ha. Farmers, foresters, and land managers in metric countries use this daily for property sizing and CAP submissions.
