Before you use this area

  • Acre is not a hectare

    1 hectare is 10,000 sq m, about 2.47 acres. Do not treat 1 acre as 10,000 sq m.

  • Square feet are different

    1 acre is also 43,560 sq ft. A square meter is larger than a square foot.

  • Local units vary

    Bigha, guntha, cent, and ground are not acres. Convert them to acres first.

  • Match the deed unit

    If the record is already in square meters or hectares, use that figure instead of reconverting.
