What does 100 mph mean?

[OmarDella]

100 mph = 100 miles = 100 km/h = 100 kilometers per hour. Here is an introduction to the related content: Driving speed: There are two ways to express the driving speed of a car, one is "kilometers per hour (Km/h)", and the other is "miles per hour (MPH)". Generally, Japanese, Korean, and most European car models are accustomed to using "kilometers per hour" to express speed, while the North American market generally prefers to use "miles per hour" to express speed. As for domestic car models, including most imported models, they all use "kilometers per hour" to express speed. Origin: The common saying of how many "ma" (a Chinese unit for speed) the speed is originated from the speed unit "mile". Originally, one mile equals 1 mile per hour, which is approximately equal to 1.6 kilometers per hour when converted to the metric system. Later, the metric system became internationally accepted."
