# How to convert from Square millimeters to Hectares

Since 1 square millimeter is equal to 0.0000000001 hectares, we could say that n square millimeters are equal to 0.0000000001 times n hectares. In other words, we could use the following formula:

hectares = square millimeters x 0.0000000001

For example, let's say that we want to convert 2.0 square millimeters to hectares. Then, we just replace square millimeters in the abovementioned formula with 2.0:

hectares = 2.0 x 0.0000000001

That is, 2.0 square millimeters are equal to 2e-10 hectares.
