How many square kilometers are in one square mile?

• A. 3.785 square kilometers
• B. 2.59 square kilometers
• C. 1.61 square kilometers
• D. 0.836 square kilometers

Answer: (B)

Converting square units requires squaring the length conversion. Since 1 mile is about 1.60934 kilometers, the area corresponding to one square mile is (1.60934 km)² ≈ 2.58999 km², which rounds to 2.59 km².

So the value that matches is about 2.59 square kilometers. The other numbers don’t fit because they either reflect the linear conversion (1.61 km per mile) or are not the result of squaring the length factor, leading to too large or too small a value.
