What is 120 miles per hour on the odometer?

[MorganDella]

Domestic speedometers are generally in KM/H, which should be referred to as 120 KM/H. However, many people say 120 "ma" or 120 "mai," which are actually misconceptions. One "ma" per hour is equivalent to one kilometer per hour. China's representation method: Since China uses the metric system for speed units, the correct unit and term for speed in China is kilometers per hour, abbreviated as Km/h in English. Foreign representation methods: On the speedometers of vehicles manufactured in China (including foreign models that use the metric system), you can see this unit designation. In a few countries like the United States and the United Kingdom, the imperial system is used, with the unit being miles per hour, abbreviated as MPH in English.
