An acre is 43,560 square feet

The acre began as the area a yoke of oxen could plough in a day and was later fixed as a furlong by a chain: 660 × 66 feet, 43,560 square feet, or 4,840 square yards. As a square it would be about 208.7 feet on each side. In metric terms an acre is 4,046.86 m² or 0.4047 hectares; a hectare is 2.471 acres. There are 640 acres in a square mile, which is why US land sections are 640 acres and quarter-sections 160.

square feet = acres × 43,560   |   acres = square feet ÷ 43,560

Reading lot sizes

A quarter-acre lot is 10,890 ft²; a third of an acre 14,520; half an acre 21,780. Suburban lots of 7,000–10,000 ft² are 0.16–0.23 acres. An American football field including end zones is 57,600 ft², about 1.32 acres, so “the size of a football field” is a bit more than an acre, not less.
