The speed of the car is 80 yards. What does the speed mean?

The "80 yards" we talk about daily refers to a vehicle speed of 80 kilometers (kilometers) per hour. The conversion relationship between "yards" and "yards" is actually YARD in imperial units and metric units: 1 A yard is approximately equal to 0.9144 meters.

The speed unit used in our country is the metric system, so the correct unit and name of speed in our country is kilometers (kilometers) per hour, and the English abbreviation is Km/h. In the United States, the United Kingdom and other countries, the unit they use is miles per hour, and the English abbreviation is MPH. Since the English name of mile is "mile", which is transliterated as "mile", miles/hour, which is also a unit of speed, is mistaken by many people as kilometers (kilometers)/hour, and is simply called "mile".

In the early days of China's liberation, most of the vehicles were American cars left behind by the Kuomintang army. At that time, the speedometer was measured in miles. Maybe because I was used to it and it was too common, I still used "miles" to indicate the speed. ” for short. Later, due to the similar pronunciation of "Ma" and "Mai", it was easy to confuse people. Many people misread "Mai" as "Ma", and they took "Ma" as the abbreviation of "×× kilometers per hour". ?
