Common Mistakes to Avoid
⚠️
1 acre is not 4,000 m2
1 acre = 4,046.86 m2 (close to 4,000 but not equal). For precision, use the full conversion. 10 acres = 40,469 m2 (not 40,000 m2).
⚠️
Confusing acres with square miles
1 square mile = 640 acres = 258.9 hectares. An acre is much smaller than a square mile.
⚠️
Section and township land terms
In US public land surveys: 1 section = 1 sq mi = 640 acres = 259 ha. 1 township = 36 sections = 23,040 acres = 9,324 ha.
