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.
