What does 'mile' mean in terms of vehicle speed?
2 Answers
It refers to miles per hour (mph, short for miles-per-hour, commonly known as 'mile'). It is a unit of speed measurement, indicating miles per hour. 1 mile = 1.609344 kilometers per hour. Other expressions of speed: 1. km/h: In daily life, 'kilometer' is often referred to as 'kilometer'. It can be expressed as kilometers per hour, km/h, km·h, kph, or kmph. Therefore, kilometers per hour is also known as 'kilometers per hour'. 2. m/s: Read as meters per second, it is a unit of speed and can be used to indicate vehicle speed. 3. Mach: Mach is a term used to express speed, also known as Mach number. One Mach is equivalent to the speed of sound: a Mach number less than 1 is subsonic, while a Mach number greater than about 5 is hypersonic; the Mach number is the ratio of the flight speed to the speed of sound at that time, with a value greater than 1 indicating supersonic speed and, similarly, less than 1 indicating subsonic speed.
I've been driving for almost thirty years and have encountered many drivers using the term 'mile' to talk about speed. Actually, this 'mile' is a transliteration of the English word 'mile,' referring to miles per hour. Many people mistakenly think it represents kilometers per hour, leading to miscalculations and speeding. A real-life example: a friend said he was driving at '60 miles,' thinking it was 60 kilometers, but it was actually close to 100 kilometers, nearly causing a high-speed crash. Remember, one mile is approximately equal to 1.6 kilometers, so be cautious with this term. Now, I set my navigation to kilometers, and the dashboard is clearer. Safety first—confusing speed units is too dangerous. I recommend beginners learn 'kilometers per hour' directly to develop good habits. Always check your speedometer while driving to avoid accidents.
