What does km/h mean in a car?

[McJohn]

On the car dashboard, km/h stands for kilometers per hour, indicating the current speed of the vehicle. km/h is the abbreviation of the English term 'kilometers per hour,' which means kilometers per hour in Chinese. The specific number is displayed on the car speedometer, showing the current driving speed of the vehicle. Additional information: Speed unit: mph 'km' means kilometers, while 'mph' is commonly referred to as 'mile.' Due to the late start of the national automotive industry, especially in the early days of the country's founding, foreign cars dominated, most of which used miles per hour as the unit for speed and odometer readings. Therefore, it has become customary to read speed in 'mile,' which means 'mile' abroad. In reality, the internationally unified speed unit is 'kilometers per hour,' and the distance of 1 kilometer and 1 mile is different, with 1 mile = 1.609 kilometers. Conversion relationship: 1 mph = 1.609344 km/h, 1 km/h = 0.6213712 mph.
