About Square feet and Hectares
Square feet (ft²): One foot squared, or 0.092903 m²; the dominant area unit in US real estate. Common uses: Home and apartment sizing in the United States, commercial real estate, lawn areas, and US construction blueprints.
Hectares (ha): Ten thousand square meters, or 100 m × 100 m; from the Greek hekaton meaning hundred (referring to the hundred-fold of an are, an obscure unit). Common uses: Land area in metric countries — agriculture, forestry, real estate (especially rural), and conservation.
How the conversion works
