One acre is 43,560 sq ft — about 90% of an American football field.
How it works
Acres = square feet ÷ 43,560. For a rectangle, square feet = length × width. For an irregular four-sided lot, this calculator averages the opposite sides: ((side 1 + side 3) ÷ 2) × ((side 2 + side 4) ÷ 2) — a close estimate for nearly rectangular lots.
Hectares = square meters ÷ 10,000.
Worked example
A lot 330 ft long and 132 ft wide is 43,560 sq ft — exactly 1.000 acre, about 4,047 m² or 0.405 hectares.
