## How to convert square miles to hectares (mi² to ha)

The formula for converting square miles to hectares is: ha = mi² × 258.999. To calculate the square mile value in hectares first substitute the square mile value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 square mile in hectares we follow these steps:

ha = mi² × 258.999

ha = 1 × 258.999

ha = 258.999

In other words, 1 square mile is equal to 258.999 hectares.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 6 square miles to hectares is:

- Understand the conversion formula: ha = mi² × 258.999
- Substitute the required value. In this case we substitute 6 for mi² so the formula becomes: ha = 6 × 258.999
- Calculate the result using the provided values. In our example the result is: 6 × 258.999 = 1553.994 ha

In summary, 6 square miles is equal to 1553.994 hectares.

## Converting hectares to square miles

In order to convert the other way around i.e. hectares to square miles, you would use the following formula: mi² = ha × 0.0038610188. To convert hectares to square miles first substitute the hectare value into the above formula, and then execute the calculation. If we wanted to calculate 1 hectare in square miles we follow these steps:

mi² = ha × 0.0038610188

mi² = 1 × 0.0038610188

mi² = 0.0038610188

Or in other words, 1 hectare is equal to 0.0038610188 square miles.
