Educational Insight

Kilometers per hour (km/h) and miles per hour (mph) are units used to measure speed. Km/h is commonly used in countries that adopt the metric system, while mph is used in countries like the United States and the United Kingdom that use the imperial system.

The difference in these units arises from the basic length units in each system: kilometers in the metric system and miles in the imperial system. This calculator helps bridge the gap between these two systems, providing an essential tool for understanding and converting speeds across different regions and applications.
