Square kilometer to Square mile

How it is calculated

Each unit is defined via the base unit (square meter (m²)). The value is first converted to the base unit, then to the selected unit.

1 km² = 1000000 m²

1 sq mi = 2589988.11034 m²

1 km² × 1000000 = 1000000 m²

1000000 m² ÷ 2589988.11034 = 0.386102158542 sq mi
