I was dumb not to know this about car’s speedometer
The dual-speed display on your car’s speedometer has some meaning, especially if you are driving in a country where the speed unit is miles. You might see two numbers on the speedometer. The top one is usually in miles per hour, while the bottom one is actually in kilometers per hour. You don’t need to calculate the speed from miles to kilometers manually!
Honestly, I was today years old when I learned about this fact, despite having used a car for more than two decades. Well, that’s how it is! I hope you’ve learned something new. Thank you!
