Quick Answer & Key Area Formulas
Direct Answer: To convert square feet to square meters, multiply by 0.09290304: m² = ft² × 0.092903. To convert square meters to square feet, multiply by 10.7639. For land, ha = acres × 0.404686 and acres = ha × 2.47105. One acre is exactly 43,560 square feet (4,046.86 m²), and one hectare is 10,000 m².
Understanding Area Units & Conversion Math
Area units are squares of length units, so their conversion factors are squared too. Because the international foot is exactly 0.3048 m, one square foot is exactly 0.3048² = 0.09290304 m². Land units like the acre and hectare are simply named multiples of these squares.
1. Square Feet to Square Meters (ft² → m²)
Square the foot-to-meter factor (0.3048 × 0.3048) and multiply. Real-estate listings in the US and UK use square feet; most of the world uses m²:
Example: a 1,500 ft² apartment × 0.09290304 = 139.35 m².
2. Acres to Hectares (ac → ha)
An international acre is 4,046.8564224 m² and a hectare is 10,000 m², so divide one by the other:
Example: 10 acres × 0.404686 = 4.047 ha.
Quick Estimates for Property & Land
For rough estimates, divide square feet by 10.76 to get square meters, and remember that 1 hectare ≈ 2.5 acres:
2,000 ft² ÷ 10.764 = 185.8 m²; 40 acres × 0.4 ≈ 16 ha (exact value: 16.19 ha).

Frequently Asked Questions
How many square feet are in a square meter?
One square meter equals 10.7639 square feet. Because 1 m = 3.28084 ft, you square that factor: 3.28084² = 10.7639.
What is the difference between an acre and a hectare?
A hectare (10,000 m²) is about 2.47 times larger than an acre (4,046.86 m²). Acres are used in the US and UK; hectares are the standard land unit in most other countries and in the EU.
How big is an acre?
An acre is 43,560 square feet — a square about 208.7 feet (63.6 m) on each side, or roughly 90% of an American football field without the end zones.
Is m² the same as sq m or sqm?
Yes. m², sq m, sqm and "square metre" all describe the same unit: the area of a square one meter on each side.
How do I calculate a room's area in square meters?
Measure length and width in meters and multiply them (4 m × 3.5 m = 14 m²). If you measured in feet, multiply the square footage by 0.0929.
