Area units compared

The square foot rules US real estate listings, while the square meter (about 10.76 ft²) is the standard almost everywhere else. For land, the acre is the classic US and UK unit: exactly 43,560 ft², or roughly 4,047 m². The metric counterpart is the hectare — 10,000 m², a square 100 meters on each side — which works out to about 2.47 acres. A square kilometer equals 100 hectares (about 247 acres), and a square mile is 640 acres. This converter moves between all of them in real time.

How big is that? Comparisons that make sense

Raw numbers are hard to picture, so it helps to anchor them to familiar things. A football field including the end zones (360 × 160 ft) covers 57,600 ft² — about 1.32 acres — so a 5-acre lot is a bit less than four football fields. A 1,000 ft² home is about 93 m², handy when browsing international listings. The tool automatically shows every value in football fields too, so you get a concrete sense of scale at a glance.
