How many kilometers per hour is one mile?

[IsaacAnn]

One mile is approximately equal to 1.6 kilometers per hour. "Mile" refers to the English word "mile," meaning a unit of distance. According to unit conversion, 1 mile equals 1609 meters or 1.609 kilometers. For example, if a car's speed is 80 miles per hour (80 mph), it is equivalent to 128.72 kilometers per hour. In the 1980s and 1990s, when China's car market was just starting, many foreign cars entered the country. At that time, speed units in Europe and America were based on the imperial system, so many speedometers displayed speed in miles per hour, abbreviated as MPH. Since the English name for mile is "mile," phonetically translated as "mai," people often omitted "per hour" when stating speed, hence the common usage of "mai" to indicate speed. Today, China uses the metric system, and speedometers display speed in kilometers per hour, which is also the speed unit adopted by most countries worldwide.
