Mileage on a car
Mileage on a car shows how far it's traveled, helping gauge its wear and value. Higher mileage often means more use and potential maintenance needs.

In Simple Terms
What it is
Mileage on a car is like a step counter for your vehicle. It tells you how many miles (or kilometers) the car has traveled since it was first driven. Think of it as a diary that keeps track of every trip, whether it’s a quick grocery run or a long road trip. The higher the number, the more the car has been used.
Why people use it
People care about mileage because it helps them understand how much "life" a car has left. Just like shoes wear out after walking too many miles, cars also experience wear and tear over time. Lower mileage often means the car is newer or hasn’t been driven much, while high mileage suggests it’s been on the road a lot.
Basic examples
Buying a used car: If you’re comparing two cars of the same age, the one with lower mileage might be a better deal because it’s been driven less.
Selling your car: A car with high mileage might sell for less because buyers assume it’s been used heavily.
Maintenance: Cars with higher mileage often need more repairs, like new tires or brakes, just like an old bike might need more tune-ups.
Mileage is a simple way to gauge a car’s history and predict future costs. It’s not the only thing that matters, but it’s a helpful starting point when thinking about a car’s condition.

Technical Details
What It Is
Mileage on a car refers to the total distance a vehicle has traveled, typically measured in miles or kilometers. It is a numerical representation of the car’s usage over time and falls under the category of vehicle metrics. Mileage serves as a key indicator of wear and tear, influencing maintenance schedules, resale value, and performance assessments.
How It Works
Mileage is tracked by an odometer, a device integrated into the car’s instrument cluster. Modern odometers use electronic sensors to monitor wheel rotations or drivetrain movements, converting these into distance measurements. The data is stored in the vehicle’s onboard computer and displayed digitally or mechanically. Older mechanical odometers use a series of gears connected to the transmission, while digital odometers rely on pulse signals from speed sensors.
