How do you convert square metres to acres and other area units?
Each area is converted to square metres, then to the target unit; for example, 1 acre = 4,046.8564 m² and 1 hectare = 10,000 m². So 1 acre = 43,560 square feet = 0.4047 hectares = 4,840 square yards. A hectare is a 100 m square, while an acre is about 4,047 m².
Understanding your result
A hectare is 10,000 m² (a 100 m square), while an acre is about 4,047 m². Both are common for land and property.
Formula and method
Each area is converted to square metres, then to the target unit. For example, 1 acre = 4,046.8564 m² and 1 hectare = 10,000 m².
Assumptions and limitations
Area conversions use the square of the corresponding length factor (1 sq ft = 0.09290304 sq m), so results are exact and rounded only for display. The tool converts a known area figure; it does not calculate area from a shape's dimensions, and land units such as the acre can vary slightly in historical or regional survey definitions not reflected here.
Worked example
1 acre = 43,560 square feet = 0.4047 hectares = 4,840 square yards.
