What does mph mean on a car dashboard?

[LeKeegan]

mph is the abbreviation for mile per hour, a unit of speed measurement, representing miles per hour, commonly referred to as "mile." 1 mile = 1.609344 kilometers per hour. Due to the late start of China's automotive industry, especially in the early days of the country's founding, foreign cars dominated the market, most of which used miles per hour as the unit for speed and odometer readings. As a result, the habit of using "mile" as a speed unit persisted. In reality, the internationally standardized unit for speed today (including in China) is "kilometers per hour," and the distance of 1 kilometer and 1 mile is not the same, with 1 mile = 1.609334 kilometers.
