When it comes to understanding speed limits or vehicle speeds, knowing how to convert kilometers per hour (km/h) to miles per hour (mph) can be quite useful, especially in countries that use different measurement systems. This article will guide you through the conversion of 120 km/h to mph.

## Understanding the Conversion

The conversion factor between kilometers and miles is:

**1 kilometer ≈ 0.621371 miles**

To convert kilometers per hour to miles per hour, you can use the following formula:

[ \text{mph} = \text{km/h} \times 0.621371 ]

## Calculating 120 km/h in mph
