What are Acres?
Acres are units of measurement used to quantify land area. An acre is a unit of area commonly used in the imperial and US customary systems, equal to 43,560 square feet or about 4,047 square meters. Originally, an acre was defined as the amount of land a yoke of oxen could plow in one day. Acres are commonly used in real estate and agriculture to measure the size of land parcels.
While acres are more commonly used in the United States and some other countries following the imperial system, hectares are the preferred unit of measurement in most of the world due to their simplicity and compatibility with the metric system.
