About these units

Acre (ac)

US & ImperialCurrent unit

43,560 square feet or exactly 4,046.8564224 m², about 40% of a hectare. Originally the area a yoke of oxen could plow in a day.

Ploughland gave the acre its name: it traces to Old Norse akr, meaning cultivated land, and is related to German Acker and Latin ager. In medieval England it was a farming measure, the land one man with a team of eight oxen could plough in a day. The traditional strip was 40 perches long and 4 perches wide, which is 660 by 66 feet, or ten square chains. The shape was never the point, and the article on the unit stresses that any area of 43,560 square feet is an acre.

An acre is 43,560 square feet, 4,840 square yards or 1/640 of a square mile, close to 0.4 hectare. For Americans, it is roughly 88 by 55 yards, about 90 percent of a football field without the end zones. The Weights and Measures Act 1878 fixed it at 4,840 square yards in Britain, where trade use ended in 1995. The 1959 international acre is exactly 4,046.8564224 m²; the US survey acre, about 4,046.872 m², differed slightly, and US survey units were retired after 2022.

1 acre = 4,046.856422 square meters (approximately).

Marla (marla)

Indian subcontinentTraditional unit (still used in some regions)

272.25 square feet (25.29 m²), a square rod (the 'big marla' in India). Used for house plots in Pakistan and north India, where sizes vary by region.

Houses in Pakistani cities such as Lahore and Islamabad are still sold as 5 marla, 10 marla or 1 kanal plots. The marla was fixed under the British Raj as one square rod, a square of 16.5 feet on a side, giving 272.25 square feet, 30.25 square yards or 25.292853 square metres. 160 marla make an acre, and 20 make a kanal.

The size depends on the country. Wikipedia says India standardized the marla at 25 square yards (about 225 square feet, or 20.9 square metres), and that in India the older, larger Pakistani-style unit is often called the big marla. Bangladesh follows the Indian definition. The same article also gives 272.25 square feet in its Indian section, so its own figures disagree, and the page is tagged as needing more citations.

In Punjab the marla is subdivided into 9 sarsahi, each a square of 5.5 feet, or 30.25 square feet. The figure used here is the 272.25 square foot Raj-era marla. Within India the unit is losing ground to the guz, square metres, acres and hectares.

1 marla = 25.29285264 square meters (exactly).
