Miles per hour and Kilometers per hour

Miles per hour

Miles per hour (mph) is a unit of speed mainly used in the United States, the United Kingdom, and other countries that do not use the metric system. It indicates the number of miles that can be covered in one hour.

A mile is an old measure that has its origin in the Roman Empire. In the imperial system, mainly used in the US and UK, a mile is equal to 5,280 feet, or approximately 1.60934 kilometers.

Kilometers per hour

Kilometers per hour (km/h) is a metric unit of speed. It indicates how many kilometers can be covered in one hour. Most countries in the world use kilometers per hour as the standard measure for traffic speeds.

A kilometer is equal to 1,000 meters. The term "kilometer" comes from the Greek words 'khilioi' and 'metron', which respectively mean "thousand" and "measure".

From Miles per hour to Kilometers per hour

Since a mile is equal to approximately 1.60934 kilometers, you can convert the number of miles per hour to kilometers per hour by multiplying by 1.60934.

1 mile per hour = 1.60934 kilometers per hour

Conversely, you can convert the number of kilometers per hour to miles per hour by dividing by 1.60934.

1 kilometer per hour = 0.62137 miles per hour

It's important to remember that while both units measure speed, they represent different amounts of distance and are therefore not interchangeable without conversion. This is especially important in contexts like driving, where correctly interpreting speed limits is essential for safe driving behavior.
