# How to convert from Hectares to Square millimeters

Since 1 hectare is equal to 10000000000 square millimeters, we could say that n hectares are equal to 10000000000 times n square millimeters. In other words, we could use the following formula:

square millimeters = hectares x 10000000000

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

square millimeters = 2 x 10000000000

That is, 2 hectares are equal to 20000000000.0 square millimeters.
