About these units
Township (twp)
36 sections: a square 6 survey miles on a side (23,040 acres). Used in US land records.
Western descriptions of land such as T2N, R3E refer to townships in the survey sense: a block six miles on a side, nominally 36 square miles or 23,040 acres. T counts six-mile steps north or south of a baseline, while R counts six-mile steps east or west of a principal meridian. Each region's grid hangs from an initial point where the two meet, and one meridian can serve several states, as the Willamette Meridian does for Oregon and Washington.
Meridians converge toward the pole, so townships would shrink to the north if nothing were done. Surveyors therefore laid standard parallels, commonly every 24 or 30 miles, to reset the width. The first lands laid out this way were the Seven Ranges in eastern Ohio, and Jefferson is credited with promoting the system to support a country of independent farmers. A survey township is distinct from a civil township, which is a unit of local government in about 20 states and may follow the survey lines or ignore them.
1 township = 93,239,944.93 square meters (approximately).

Acre (ac)
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).
