How many hectares is an acre
One acre is exactly 0.40468564224 hectares, a bit over four tenths. In square meters that is 4,046.86 m², and in square feet 43,560 ft². A hectare is 10,000 m², a square 100 meters on each side, and equals about 2.4711 acres.
Acres to hectares formula
Multiply the acres by 0.40468564224:
ha = acres × 0.40468564224
Multiplying by 0.4 is a fair estimate that runs about 1.2 percent low: 500 acres × 0.4 is 200 ha, against an exact 202.34 ha. Dividing by 2.471 gives the same exact answer from the other direction.
