What is a Square Mile?
A square mile is a commonly known unit for measuring area or land area, that is widely used in the imperial as well as the US measurement systems. Often abbreviated as sq. mi and mi2, a square mile is equal to a square measuring one mile on every side and works out to exactly 2.59 square kilometers. You should not consider the unit to be the same as miles square referring to a square region where each side has a specified length.
A square mile is also used as a standard unit to calculate the population figures in a specified area. Therefore, the population figures are often considered as the number of people for each square mile. The total population figure in a square mile is calculated by dividing the total number of people by the number of square miles in area. A square mile is equal to 640 acres, 27,878,400 square feet, 3,097,600 square yards, 27,878,400 square feet, 3,097,600 square yards, 25,899,881,103.36 square centimetres, 2,589,988.110336 square metres, 258.9988110336 hectares

Formula for Converting Square Miles to Square Kilometers
Since we know there are 2.589988 square kilometers in one square mile, use the below simple formula for the conversion:
Square Kilometers = Square Miles x 2.589988
Below are a few examples for converting Square Mile to Square Kilometres. Take a look:
Example 1: Convert 5 Square Miles to Square Kilometers
Solution 1: Using the above formula, we will get:
5 sq mi = (5 x 2.589988) = 12.949941 sq km
Hence, 5 sq mi is equal to 12.949941 sq km.
Example 2: Convert 20 Square Miles to Square Kilometers
Solution 2: Just like above,
20 sq mi = (20 x 2.589988) = 51.79976 sq km
Hence, 20 sq mi is equal to 51.79976 sq km.
Example 3: 1000 Square Miles to Square Kilometers
Solution 3: Again,
1000 sq mi = (1000 x 2.589988) = 2,589.988 sq km
Hence, 1000 sq mi is equal to 2,589.988 sq km.
