Common mistake

Confusing acres with hectares: a hectare is 2.47 acres, so a "10-hectare farm" is nearly 25 acres. Also, an acre is not a fixed shape — historically a furlong by a chain (660 × 66 ft), but any shape with 43,560 ft² is one acre.

Quick answer: one acre equals 4,046.86 square meters. So to convert acres to square meters, multiply by 4,046.8564224.
