Calculator for Converting Acres to Bighas.

The acre has a long and storied history as a unit of land measurement, with its origins dating back centuries. Originally used predominantly throughout the British Empire, the Anglo-Saxon acre was defined by a strip of land that measured 1 × 1/10 furlong, or 40 × 4 rods (660 × 66 feet).

In modern times, the acre is utilized in both the imperial and US systems of units, with one acre equaling 4,840 square yards, 43,560 square feet, 4,047 square metres, or 0.4047 hectares. Another definition describes an acre as an area one furlong long by 4 rods wide.

It's worth noting that imperial units were the official weights and measures used in Great Britain from 1824 until the adoption of the metric system starting in 1965. Today, imperial units are defined in metric terms and are also included in the US Customary System, which originated from the British Imperial System.

The word "acre" derives from an ancient English term, "aker," which denotes an "open field." Interestingly, there's no prescribed shape for an acre measure. While the full name is often used, some also refer to an acre using the abbreviation "ac."

The acre is a widely used measurement unit all over the world, including in countries such as Canada, Jamaica, Spain, France, Germany and most of South Asia, including India, Pakistan, Sri Lanka, and Bangladesh. However, the United Kingdom is where the unit is most commonly used. In medieval England, an acre of land was defined as an area that a yoke of oxen could plough in one day. The acre became popular across the British Empire, and the size of farms is still usually expressed in acres, even though expressing them in square miles might make more sense due to the large numbers involved.

It's important to note that there is no standard measurement of an acre, and its definition varies by country. For example, an acre of land in Scotland is equivalent to 1.27 standard acres, while the Irish acre is equal to 1.6 British or US acres.

In India, residential plots are typically measured in square feet, while agricultural land is measured in acres or hectares. However, the unit "bigha" is more commonly used in northern parts of the country. Bigha measures can vary by state, so the bigha-acre conversion would show different values depending on where the land is located.
