How do you convert kilometers to square kilometers?

You can't. SQ in is an area measure while kilometers measure distance.

Multiply square km by 0.39 to get approximate square miles.

1km = 1000m 1 sq km = 1km x 1km = 1000m x 1000m = 1 000 000 sq m Thus to convert meter square to kilometer square divide by 1 000 000 (a million)

You divide the number of square meters by a million.

Formula: square miles x 2.6 = square kilometers.
