# How to convert from Square miles to Hectares

Since 1 square mile is equal to 258.9988110336 hectares, we could say that n square miles are equal to 258.9988110336 times n hectares. In other words, we could use the following formula:

hectares = square miles x 258.9988110336

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

hectares = 2 x 258.9988110336

That is, 2 square miles are equal to 517.997622067 hectares.
