Convert square mile to hectare
square mile
Definition: The square mile (symbol: sq mi or mi2) is a unit of area in the imperial and United States customary (UCS) systems of units. It is defined as the area of a square with side lengths of one statute mile (5,280 feet). A square mile is a large area that is equal to 27,878,400 square feet, 3,097,600 square yards, and 640 acres.
History/origin: Area is commonly represented in the form of a square with sides of a specific unit of length, written as "square" followed by the chosen unit of length. The square mile is one of many such units and is derived from the area of a square with sides of one mile.
Current use: Square miles are used when the measurement involves large scales such as country sizes. It can be used when referencing population studies, such as a measurement of total population per square mile. As an imperial and USC unit, it is most commonly used in countries that use these systems of measurement. In countries that have adopted the International System of Units, the square meter (and its subsequent multiples and submultiples) is the preferred system of measurement.
hectare
Definition: A hectare (symbol: ha) is a unit of area that is accepted in the International System of Units (SI). It is primarily used to measure land area. One hectare is equal to 10,000 square meters and is equivalent to approximately 2.471 acres.
Current use: Hectares are primarily used to measure land area around the world. Even though it is not an SI unit (just a unit accepted for use with SI) the SI brochure states that the use of the hectare is expected to "continue indefinitely."
