What is the odometer of a car?

An odometer is a device that measures and displays the distance traveled by a vehicle. It is typically located on the dashboard of a car and is visible to the driver. Odometers are used to record the total distance traveled by a vehicle over its lifetime, as well as to measure the distance traveled between two points. Some odometers also display the average speed of the vehicle over a certain period of time.

Odometers work by using a sensor to measure the rotation of the wheels of the vehicle. This information is then sent to an electronic control unit (ECU), which calculates the distance traveled and displays it on the odometer.

Odometers are an important tool for drivers, as they provide information that can be used to determine fuel efficiency, track maintenance intervals, and calculate the cost of operating a vehicle.
