m² = mi² × 2589988.110336One square mile equals 2.59 km² or about 2.59 million m². This conversion is fundamental in US geography — counties, national parks, and cities are often measured in mi² while scientific and international contexts use km² or m². Environmental scientists and regional planners convert between these frequently.
