## How to convert from ACRES to HECTARES

Since 1 acre is equal to 0.405 hectares, we could say that n acres are equal to 0.405 times n hectares. In other words, we could use the following formula:

hectares = acres x 0.405

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

hectares = 2.0 x 0.405

That is, 2.0 acres are equal to 0.809 hectares.
