mph to kmh

The term **'mph to kmh'** refers to the conversion between two units of speed: **miles per hour (mph)** and **kilometers per hour (km/h or kmh)**. It is commonly used to convert speed measurements from the imperial system (used primarily in the United States and a few other countries) to the metric system (used in most of the world).

The conversion factor is:
**1 mph = 1.60934 km/h**

So, to convert mph to kmh, you multiply the number of miles per hour by 1.60934.
