Square meters
The square metre is the SI derived unit of area, defined as the area of a square whose sides each measure exactly one metre. It is the standard unit for floor areas in architecture and real estate, land parcels in urban planning, and cross-sectional areas in engineering. The surface area of a tennis court is approximately 260 m², a standard football pitch about 7,140 m², and a hectare equals exactly 10,000 m².
Acres
The acre is a unit of area equal to exactly 4,046.8564224 square metres, the standard unit for land measurement in the United States and United Kingdom. Its origin lies in medieval English agriculture: an acre was the amount of land a yoke of oxen could plough in a single day, standardised as a furlong (220 yards) long and a chain (22 yards) wide — exactly 43,560 square feet. One square mile contains exactly 640 acres.
