$1 mi2 = 2, 589, 988.11 m2$
3
Forward conversion
$1 km2 = \frac{1 , 000 , 000 m2}{2 , 589 , 988.11 m2} \times 1 mi2 = \frac{1 , 000 , 000}{2 , 589 , 988.11} mi2 = 0.386102158593 mi2$
4
Reverse conversion
$1 mi2 = \frac{2 , 589 , 988.11 m2}{1 , 000 , 000 m2} \times 1 km2 = \frac{2 , 589 , 988.11}{1 , 000 , 000} km2 = 2.58998811 km2$

1 km2 = 0.386102158593 mi2.

10 km2 = 3.86102158593 mi2.
