What is the calculation formula for vehicle mileage?

The principle of how a car odometer calculates mileage is based on the number of rotations the tires make. Below are the relevant explanations: 1. Standard configuration at factory: With fixed specifications, the tire circumference is standardized, so the distance traveled per rotation is constant. Standard tire parameters are preset in the vehicle's computer. Using standard tires ensures the computer-calculated mileage matches the actual distance traveled. 2. Additional information: Vehicle speedometers are divided into two types: roller counters and dot-matrix LCD screens. They consist of a speedometer indicating the vehicle's speed and an odometer recording the distance traveled, both housed in a common casing and driven by the same shaft. Conventional speedometers are generally inductive.
I've driven quite a few cars, and I feel that mileage is simply the distance you've traveled, usually displayed on the dashboard in kilometers or miles. There's a small sensor inside the vehicle that counts how many times the wheels have rotated, then calculates the actual distance based on the size of the wheels—similar to how total mileage equals the number of wheel rotations multiplied by how far the car moves per rotation. If you want to estimate the mileage of a single trip, you can use the old method of multiplying speed by time, like driving at 100 km/h for one hour would cover 100 km. But in reality, speed is always changing, so the dashboard data is the most accurate. I value mileage mainly because it reminds me of maintenance schedules. For example, my car needs an oil change every 5,000 km, or the engine could develop problems. Additionally, high-mileage vehicles require more frequent checks on brakes and tire safety. In short, don't overcomplicate daily driving with formulas—paying attention to your car is what matters most.
As a car owner who often researches fuel consumption, I must say that calculating mileage is straightforward. The vehicle's dashboard directly records the number of wheel rotations, and the formula is the number of wheel rotations multiplied by the wheel circumference to get the total distance. However, the formula people care more about is average fuel efficiency, such as MPG, which indicates how many miles can be driven per gallon of fuel. Specifically, it's the driving distance divided by fuel consumption. For example, if you drive 200 kilometers using 10 liters of fuel, the MPG is approximately 20 kilometers per liter. This can help you save money—lower fuel consumption means fewer refuels. I've tried using an app to record mileage and fuel consumption data, and by adjusting my driving habits based on the comparison, I saved a significant amount on fuel costs in a year. Also, when the mileage is high, pay attention to the vehicle's condition to avoid being tricked by odometer fraud.
