Conversion formula
Every conversion here uses the published factor, not a rounded one.
Example: Square meters to Square feet
1 m² = 10.76391 ft²
To convert square meters to square feet, multiply by 10.76391:
50 m² = 538.1955 ft²
Figures on this page are shown to seven significant digits. The converter keeps the full precision and rounds only what it displays.
Did you know?
An acre is exactly 43,560 square feet — an odd-looking number that comes from an old measure of one chain by one furlong.
A hectare is simpler: exactly 10,000 m², or a square 100 m on each side, which works out at about 2.471 acres.

Unit guide
Square units, acres, and hectares
Area measures a two-dimensional surface. A linear factor must be squared: because 1 foot is 0.3048 meters, 1 square foot is 0.3048², or 0.09290304 square meters.
Square meter and kilometer (m², km²)
Square meters suit rooms and floor plans; square kilometers suit cities and regions.
Square inch, foot, and yard (in², ft², yd²)
US customary units for materials, rooms, lots, and construction.
Acre and hectare (ac, ha)
Land units. One hectare is 10,000 m²; one acre is exactly 4,046.8564224 m².
How the math works
Area conversion formulas
- Square meters to square feetsquare feet = square meters ÷ 0.09290304Example: 100 m² = 1,076.39104 ft²
- Acres to square meterssquare meters = acres × 4,046.8564224Example: 2 ac = 8,093.7128448 m²

Context
Where area units are used
Square feet and square meters appear in property listings, building plans, flooring estimates, and room measurements. Always preserve the squared symbol so an area is not mistaken for a length.
Acres are common in US land listings. Hectares are common in agriculture and metric land records, while square kilometers and square miles suit much larger geographic areas.
