Convert acre to square inch
acre
Definition: An acre (symbol: ac) is a unit of land area used in the imperial and US customary systems. It is defined as the area of 1 chain (66 feet) by 1 furlong (660 feet), which is exactly equal to 1/640 of a square mile, 43,560 square feet, or exactly 4046.8564224 square meters.
History/origin: In the Middle Ages, the acre was defined as the area that a yoke (pair) of oxen could typically plow within one day, using a wooden plow. Before the metric system was adopted, many countries used their own versions of the acre. The most commonly used acre today, the international acre, is based on the international yard, which was defined in 1959.
Current use: Acres are used in countries including the United States, the UK, Ghana, India, Canada, and others. The United States (US) uses both international as well as US survey acres (~4047 square meters), which vary based on which type of yard is used in the measurement. However, area measurements are typically not accurate enough for the difference between the two acre measurements to be detectable.
square inch
Definition: Square inch is a measure of area, the extent of a two-dimensional surface. For conversion purposes, its value is 0.00064516 times the reference unit, square meter.
