## How to convert square miles to square kilometers (mi² to km²)

The formula for converting square miles to square kilometers is: km² = mi² × 2.58999. To calculate the square mile value in square kilometers first substitute the square mile value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 square mile in square kilometers we follow these steps:

km² = mi² × 2.58999

km² = 1 × 2.58999

km² = 2.58999

In other words, 1 square mile is equal to 2.58999 square kilometers.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 5 square miles to square kilometers is:

- Understand the conversion formula: km² = mi² × 2.58999
- Substitute the required value. In this case we substitute 5 for mi² so the formula becomes: km² = 5 × 2.58999
- Calculate the result using the provided values. In our example the result is: 5 × 2.58999 = 12.94995 km²

In summary, 5 square miles is equal to 12.94995 square kilometers.

## Converting square kilometers to square miles

Converting square kilometers (km²) to square miles (mi²) involves changing the unit of area measurement from the metric system (square kilometers) to the imperial or US customary system (square miles). Here's a detailed explanation of how to perform this conversion.### Step 1: Understand the Conversion Factor

To convert square kilometers to square miles, you need to know the conversion factor between these two units. The conversion factor is as follows:1 square kilometer (km²) is approximately equal to 0.386102 square miles (mi²).This approximation is based on the conversion between kilometers and miles for linear distance and involves squaring it for area.### Step 2: Set Up the Conversion

To perform the conversion, you'll use this conversion factor in a mathematical equation. The general formula for converting square kilometers to square miles is:Square Miles (mi²) = Square Kilometers (km²) × Conversion Factor### Step 3: Perform the Calculation

Now, let's apply this formula with an example:Suppose you have an area of land that measures 50 square kilometers, and you want to know its equivalent in square miles: Square Miles (mi²) = 50km² × 0.386102 (conversion factor)### Step 4: Calculate the Result

Square Miles (mi²) = 50km² × 0.386102So, 50 square kilometers is approximately equal to 19.3051 square miles.It's important to remember that this is an approximation because the conversion factor used here is rounded. For precise conversions, especially in scientific or legal contexts, more accurate conversion factors can be used. However, for most everyday purposes, the approximate conversion factor should suffice.In summary, converting square kilometers to square miles involves multiplying the number of square kilometers by the conversion factor, which is approximately 0.386102. This process allows you to express an area measurement in the metric system (km²) in terms of the imperial or US customary system (mi²).## Conversion Unit Definitions
