About Acre (ac)
An imperial unit of land area equal to 43,560 square feet (about 4,047 m² or 0.405 hectares), historically defined as the area one ox-team could plow in a day. The acre remains the standard US and UK unit for agricultural land, real estate over a certain size, forestry, ranch/farm sales, zoning, and golf-course dimensions. A US football field (including end zones) is about 1.32 acres; Central Park in New York is 843 acres.
About Square Meter (m²)
The SI derived unit of area, equal to a square with sides of one meter. Square meters are the global standard for floor-plan area in real estate, room measurements, building codes, and scientific work. A typical hotel room is about 25 m²; a basketball court is 420 m²; a standard ISO shipping container floor is ~14.5 m². The square meter is the base unit for every SI-derived areal quantity including pressure, surface tension, and heat flux.
