# How to convert from Square inches to Square kilometers

Since 1 square inch is equal to 0.00000000064516 square kilometers, we could say that n square inches are equal to 0.00000000064516 times n square kilometers. In other words, we could use the following formula:

square kilometers = square inches x 0.00000000064516

For example, let's say that we want to convert 2 square inches to square kilometers. Then, we just replace square inches in the abovementioned formula with 2:

square kilometers = 2 x 0.00000000064516

That is, 2 square inches are equal to 1.29032e-09 square kilometers.
