In our country, everyone generally uses two units of kilometers and kilometers for distance and mileage in daily life, 1000 meters = 1 kilometer = 1 kilometer. For the speed is generally used to use km / h units to express, that is, the usual colloquial speed, XX kilometers per hour, so the general family car our dashboard on the speedometer displayed the numerical unit is km / h, such as speed is 50 km / h, which means that if at a uniform speed, the vehicle will travel 50 km per hour.
But in the past two years, when talking about the speed of the car, many friends around me have begun to use the two units of measurement of the mile and the code, such as: I was driving 100 miles on the high speed, and there was a sudden accident in front of me, and I braked sharply; or: a violent operation, the speed was 60 yards...
It may also be a trend, or it may be confusing the concept, but the brother has always been more rigorous about car data, so we must seriously come to science with you to popularize the "mai" and "code" these two speed measurement units are different from the kilometers and kilometers we usually use.
Understand these knowledge points, the next time you go out to brag with friends, you can not only avoid embarrassing situations, but also throw out professional knowledge points. Secretly tell you that girls like this kind of learned boy the most! Hurry up and learn!
What unit is "Mai"
"Mai" is actually derived from the Chinese pronunciation of mile (mile), which is a unit of length 1 mile = 1 mile, which is widely used in Western countries such as the United States and the United Kingdom, just like our country uses kilometers (km) to do the unit of measurement. When miles are used as a unit of speed, the full name is XX miles per hour, which translates to English as Miles Per Hour, so its abbreviation is mph.
Careful people will find that the three letters of mph are often seen on the dashboard of some imported models, especially on the dashboard of parallel imported cars. This is because in some European countries it is customary to use miles as a unit, so the car dashboard also uses miles (mph) to indicate the speed of the vehicle.
How much is the difference between miles and kilometers?
1 km = 0.6213712 miles
100 km = 62.1371192 miles
Before I understood brother, there was a friend Xiao Tang, taking an imported SUV from his father's relatives to drive to the surrounding cities to run errands, but after returning, his relatives called to say that they had received several speeding tickets and asked Xiao Tang how he drove the car that day. Xiao Tang said that he was very aggrieved, he honestly drove, there was no speeding during the whole process, but he did not know why he received several tickets.
In the end, it was clear that it turned out that Xiao Tang did not see the measurement unit on the dashboard when driving, and the imported SUV dashboard used mph as the display unit, so when Xiao Tang drove 100mph on the highway, the actual speed had reached 160km/h! No wonder you get a speeding ticket.
What unit is the "code"
"Code" is a British unit of length with the English name yard, abbreviated yd, which is mainly used in countries such as the United Kingdom, its former colonies and the Commonwealth, and the United States also uses such a unit of measurement.
So how many meters is 1 yard equal?
1 yard = 0.9144 m = 0.000914 km
100 yards equals 0.09144 km
Write at the end:
Usually, when everyone is chatting, when it comes to the "mile" and "code" behind the speed, we all know that we are expressing the speed of the "kilometer system", but from a rigorous point of view, the speed gap between the three ≠ yards ≠ kilometers is still very large, and everyone should still pay attention to the distinction. Especially when driving with unfamiliar models, pay attention to whether the speedometer unit on the dashboard is km or mph to avoid problems such as speeding. There are also some dashboards, the outer ring is the mph value, the inner ring is the km/h value, so also pay attention to the distinction.
