How it works
- Converted value = × f₁ ÷ f₂; SI: m²
- Worked example: 1 ha = 10,000 m²; 1 ft² = 0.09290304 m²
- Supported input limits: : 0 ≤ x ≤ 1,000,000,000,000

Assumptions and limitations
Area factors are squared length factors: one square foot is 0.09290304 m². The acre is the international acre, and one hectare is 10,000 m². This converts an area you already know; it does not determine plot boundaries or usable floor area.
