An acre is a unit of measurement which directly relates to the square mile and is commonly used to describe the size of a piece of land. An acre does not take on a particular set shape. Acreage is a plural form of acre used to describe land containing multiple acres.
One acre consists of 4,840 square yards, 43,560 square feet, or 4,050 square meters. In contrast, one square mile consists of 640 acres. For visualization purposes, one acre is roughly the size of a standard American football field, not including end zones.
The acre unit of measurement is most frequently used in the United States and other smaller countries that still rely on using the Imperial System for measurements. In the United Kingdom, which uses the metric system, the hectare is the preferred unit of measurement. One acre is approximately 40% the size of a hectare.
The history of the acre dates back hundreds and hundreds of years, deriving from the Old English word “æcer” which meant an open field. The acre was said to be a measurement of the amount of land that one man and his ox could till in one single day.
Our acreage calculator can be used with any of the following shapes of land: parallelogram, rectangle, rhombus, square, trapezoid, or triangle. While most standard land lots, especially city lots, are generally rectangular, it’s not entirely rare to come across acreage with an unusual shape, especially in the country.
One great use for the acreage calculator is when you are buying or selling land or a house and you need to convert your lot size into acres. Simply enter the shape and dimensions of your land and the acreage calculator will do the rest.
