What does km/h mean on a car?

km/h stands for kilometers per hour, indicating the current speed of the vehicle. Below is a related introduction: 1. Definition: km/h is the abbreviation for 'kilometers per hour' in English, specifically displayed on the car's speedometer to show your current driving speed. 'km' stands for kilometers, representing the distance traveled by the vehicle. 2. Speed conversion: 1 meter per second (m/s) = 3.6 kilometers per hour (km/h). 'km' refers to kilometers, where 1 kilometer = 1000 meters = 1 kilometer. The conversion method is to divide km/h by 3.6 to get m/s, or multiply m/s by 3.6 to get km/h. The conversion process is as follows: 1 km/h = 1000 m / 3600 s = (1/3.6) m/s, so 1 m/s = 3.6 km/h.
Every time I drive, I keep an eye on the km/h on the dashboard, which stands for kilometers per hour. For example, a speed limit of 120km/h on the highway means you can drive 120 kilometers in one hour. This unit is different from the commonly used mph abroad, where 1 mile is approximately 1.6 kilometers. So, seeing 70mph in the U.S. is roughly equivalent to our 110km/h. It's important to pay attention to this value while driving. In urban areas, the speed limit is generally 60km/h, and exceeding it is not only dangerous but can also be caught by speed cameras. I recommend beginners use mobile navigation for assistance, as it provides voice prompts for the current speed, which is especially useful. I remember one time on the highway when I wasn't paying attention and ended up exceeding the limit by 20km/h, resulting in a fine. Now, I've developed a habit of glancing at the dashboard every ten minutes.
