About Acre

About Acre

About Acre


An acre is a measurement unit of land area. Arce is not a metric unit. It is used to measure an area, used in the imperial and US customary systems.
It measures 43,560 square feet or 4,046.873 square meters. In mediaeval times, it was defined as the area that could be ploughed in a single day with the help of an ox.


The origin of the acre is uncertain, but it was used in medieval England and was defined as a strip of land 1 furlong in length and 4 rods (or poles) in width.
The word itself is derived from the Old English ‘aecer’, which literally translates to “open field”.

A hectare is a unit of area, which is used to measure land area. A hectare is defined as the area equal to 10,000 square meters or 2.471 acres.


The term “hectare” was originally used in the French metric system and was derived from the Latin “hecto,” which means “hundred.” It is believed to have been first used by the French astronomer Joseph-Jérôme Le Français de Lalande in 1795 as a unit of measure for the area of land around his observatory. The hectare was later adopted by many other countries and it is used for measurement of area.

Both the acre and the hectare are important measurements of area that are still in use around the world today. While the acre is mostly used in non-metric countries, such as the U.S, Canada, the UK, and Ireland, the hectare is still firmly entrenched in many parts of Europe, Asia, and Africa. Though they differ in units to measure and size, both are essential tools for measuring land.
