Converting kilometers per hour (km/h) to miles per hour (mph) is a common process in physics and in everyday life, especially when working with international measures of speed. One mile per hour equals approximately 1.60934 kilometers per hour.

So if you want to convert a speed from kilometers per hour to miles per hour, divide the number of kilometers per hour by 1.60934.

**Formula: mph = km/h / 1.60934**

Conversely, if you want to convert a speed from miles per hour to kilometers per hour, multiply the number of miles per hour by 1.60934.

**Formula: km/h = mph * 1.60934**

Please note that these conversions are based on the international mileage system and do not apply to other mileage systems (such as the nautical mile).
