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).

Guntha (guntha)

Indian subcontinentTraditional unit (still used in some regions)

1,089 square feet (about 101.17 m²). A land unit used in Maharashtra, Gujarat and Karnataka; 40 guntha make an acre.

A guntha is a small land measure used on the Indian subcontinent, and in India it is defined as a square 33 feet on a side. That gives 1,089 square feet, or about 101.17 square metres (120.999 square yards), and 40 gunthas make one acre. The guntha therefore acts as the fraction below the acre in plot sizes.

The size changes across the border. In Pakistan the unit is counted as 120 square yards, with 4 guntha to a jareeb and 10 jareeb to an acre, so the 40-to-an-acre ratio survives even though the guntha itself is a little smaller. Sub-units differ as well. In India a guntha holds 16 annas of about 6.32 square metres each, while in Pakistan 6 annas of 20.16 square yards make a guntha.

Wikipedia cites a 1966 United Nations handbook for the Pakistani values and says the units were used alongside the Imperial measures. The figure used here is the Indian one, 1,089 square feet. In metric terms a guntha is a little over 100 square metres.

1 guntha = 101.1714106 square meters (approximately).
