The acre is an imperial or US customary unit for measuring land. Conventionally, it is defined as the area one square mile in area. A square mile measures 640 acres (2.59 km2). ..

The imperial system of measurement is different from the metric system in that there are different scales for measuring things. For example, an acre is the equivalent of 43,560 square feet, but there is no specific unit for measuring land in the imperial system. ..
Measuring
This system was used back then, when there were no calculators and computers because it could measure the land with a chain measure and then easily calculate the area. But not all pieces of land would be in the fashion as an acre is traditionally defined. Odd-shaped lands could be divided into smaller parts of a standard shape. Then each area would be measured using a chain, and it could be added up. Nowadays, it is more easy to find the square footage and then calculate the number of acres.
How An Acre Became A Measuring Unit?
The word “acre” originated from the Old English word æcer, which means “open field”—the origin dates to the olden days. When ploughing with a yoke of oxen, the animals (and the farmer) had a practice of resting after ploughing a furrow for 1/8 of a mile. As a result, 1/8 of a mile has come to be known as furrow-long or furlong. Furlongs are not really in use anymore except for the exception of measuring horse racing tracks. As a practice, the farmers used to plough a furlong and then turned around and ploughed in the other direction. These lands were laid out so that they could finish a land every ten rounds with a 10-inch ploughshare (total of about 16.5 feet).
The farmers used to start early in the morning and finish about two lands by noon. At noon they would stop for lunch and feed and water the animals. After the noon break, they could complete two more lands. So, in total, a good day’s work would be about four lands, or 40 rounds (80 furrows) measured 16.5 × 4 = 66 feet across by a furlong (660 feet). Therefore, this area of 43,560 feet ploughed became the standard unit of measuring land called an acre. Since this unit of measuring land has been used for a long time, it is carried over and is in practice even today.
Comparing An Acre
This numerical jargon might confuse you, and you might not be getting a good idea of how big an acre is. The best way to see this is by comparing it with things in everyday life. An acre of land can fit about 15.5 tennis courts, 9.3 basketball courts, and 18 houses with an area of 2400 square feet. ..
Conclusion
An acre is an imperial unit of measuring land area equal to 43,560 square feet, or measuring 4046.86 square meters. It originated as the area of land that an ox can plough in one day. The size of an acre can be visualized as equal to 18 suburban houses. Despite more concrete metric units, acres are still being used as a unit to measure land, as it has been in practice since the Middle Ages.
The imperial unit is the square foot. The square foot is equal to an acre of land.
