## How to convert miles per hour to kilometers per hour (mph to km/h)

The formula for converting miles per hour to kilometers per hour is: km/h = mph × 1.60934400009669. To calculate the mile per hour value in kilometers per hour first substitute the mile per hour value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 mile per hour in kilometers per hour we follow these steps:

km/h = mph × 1.60934400009669

km/h = 1 × 1.60934400009669

km/h = 1.60934400009669

In other words, 1 mile per hour is equal to 1.60934400009669 kilometers per hour.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 9 miles per hour to kilometers per hour is:

- Understand the conversion formula: km/h = mph × 1.60934400009669
- Substitute the required value. In this case we substitute 9 for mph so the formula becomes: km/h = 9 × 1.60934400009669
- Calculate the result using the provided values. In our example the result is: 9 × 1.60934400009669 = 14.48409600087021 km/h

In summary, 9 miles per hour is equal to 14.48409600087021 kilometers per hour.

## Converting kilometers per hour to miles per hour

In order to convert the other way around i.e. kilometers per hour to miles per hour, you would use the following formula: mph = km/h × 0.6213711922. To convert kilometers per hour to miles per hour first substitute the kilometer per hour value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilometer per hour in miles per hour we follow these steps:

mph = km/h × 0.6213711922

mph = 1 × 0.6213711922

mph = 0.6213711922

Or in other words, 1 kilometer per hour is equal to 0.6213711922 miles per hour.
