Acres

[X] acres = 640 × [Y] sq mi

where [X] is the result in acres and [Y] is the amount of sq mi we want to convert

where [X] is the result in acres and [Y] is the amount of sq mi we want to convert

40 sq mi to acres conversion result above is displayed in three different forms: as a decimal (which could be rounded), in scientific notation (scientific form, standard index form or standard form in the United Kingdom) and as a fraction (exact result). Every display form has its own advantages and in different situations particular form is more convenient than another. For example usage of scientific notation when working with big numbers is recommended due to easier reading and comprehension. Usage of fractions is recommended when more precision is needed.
