How many miles is 25km/h?

[MacWyatt]

25km/h refers to 25 miles. Generally speaking, a speed of 100 miles equals 100 kilometers per hour, while 100 miles as referred to by the British equals 160 kilometers per hour. Therefore, 25km/h means 25 miles, whereas in foreign countries it means 40 miles. The specific details are as follows: Introduction to miles: A speed of 25 miles can travel approximately 25 kilometers in one hour. A mile is an imperial unit of length, approximately equal to 0.9144 meters. As is well known, the speed of a car is calculated in the metric unit of kilometers, typically in tens of kilometers. One kilometer equals 1000 meters, so tens of kilometers means tens of thousands of meters. Origin of car speed units: Cars originated from foreign countries, and the original unit for measuring speed was mile. The speedometer on the car was also marked in miles. At that time, the general public was largely unfamiliar with English, and upon hearing the term mile, they didn't understand its meaning, only knowing that it referred to the car's speed. To make it easier for the general public to read, mile was transliterated into "mile." Thus, mile became the unit for measuring car speed. In other words, mile is a loanword from English, meaning mile.
