# How to convert from Acres to Square kilometers

Since 1 acre is equal to 0.0040468564224 square kilometers, we could say that n acres are equal to 0.0040468564224 times n square kilometers. In other words, we could use the following formula:

square kilometers = acres x 0.0040468564224

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

square kilometers = 2 x 0.0040468564224

That is, 2 acres are equal to 0.0080937128448 square kilometers.
