## How to convert kilometers per second to miles per second (km/s to mi/s)

The formula for converting kilometers per second to miles per second is: mi/s = km/s × 0.6213711922. To calculate the kilometer per second value in miles per second first substitute the kilometer per second value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 kilometer per second in miles per second we follow these steps:

mi/s = km/s × 0.6213711922

mi/s = 1 × 0.6213711922

mi/s = 0.6213711922

In other words, 1 kilometer per second is equal to 0.6213711922 miles per second.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 2 kilometers per second to miles per second is:

- Understand the conversion formula: mi/s = km/s × 0.6213711922
- Substitute the required value. In this case we substitute 2 for km/s so the formula becomes: mi/s = 2 × 0.6213711922
- Calculate the result using the provided values. In our example the result is: 2 × 0.6213711922 = 1.2427423844 mi/s

In summary, 2 kilometers per second is equal to 1.2427423844 miles per second.

## Converting miles per second to kilometers per second

In order to convert the other way around i.e. miles per second to kilometers per second, you would use the following formula: km/s = mi/s × 1.60934400009669. To convert miles per second to kilometers per second first substitute the mile per second value into the above formula, and then execute the calculation. If we wanted to calculate 1 mile per second in kilometers per second we follow these steps:

km/s = mi/s × 1.60934400009669

km/s = 1 × 1.60934400009669

km/s = 1.60934400009669

Or in other words, 1 mile per second is equal to 1.60934400009669 kilometers per second.
