What does 100 mph mean?
2 Answers
100 mph = 100 miles = 100 km/h = 100 kilometers per hour. Driving speed: There are two ways to express the driving speed of a car, one is "kilometers per hour (Km/h)", and the other is "miles per hour (MPH)". Generally, Japanese and Korean car models and most European car models are accustomed to using "kilometers per hour" to indicate speed, while the North American market usually uses "miles per hour" to indicate speed. As for domestic car models, including most imported models, they all use "kilometers per hour" to indicate speed. Origin of the term "mph": The common saying of how many mph a car is going originates from the speed unit "mile". Originally, one mile equaled 1 mile per hour, which is approximately equal to 1.6 kilometers per hour when converted to the metric system. Later, the metric system became internationally common.
When people casually mention driving at 100 'ma', it's actually a common misunderstanding of the unit. In Chinese, the term 'ma' is often misused; the correct units should be kilometers per hour (km/h) or miles per hour (mph). Typically, the number displayed on the car's dashboard is the reference speed. 100 kilometers per hour is equivalent to the maximum allowed speed on regular highways, where the car might feel a bit floaty, wind noise increases, and it's essential to maintain a safe distance. If it's 100 miles per hour, that's speeding, as speed limits are usually below 120 km/h, making it extremely dangerous. As a long-time car enthusiast, I recommend checking tire pressure before every drive. High speeds accelerate tire wear and significantly increase fuel consumption. Remember, safe driving comes first—don't chase speed.
