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

km² = ha × 0.01

One hectare equals 0.01 km² — by definition, since 1 ha = 10,000 m² and 1 km² = 1,000,000 m². This is one of the cleanest area conversions. Land managers in metric countries often think in hectares for properties and km² for regional planning — converting between them just means moving the decimal point.
