The odometer of an automobile measures the total distance traveled by the vehicle. It provides a numerical reading, usually displayed in miles or kilometers, indicating how far the vehicle has moved since it was first used or since the last reset (if applicable)

How the Odometer Works

• The odometer operates based on the rotation of the vehicle's wheels. Each full rotation corresponds to the vehicle traveling a distance equal to the circumference of the wheel.
• By counting the number of wheel rotations and multiplying by the wheel's circumference, the odometer calculates the total distance covered

• Mechanical odometers use a system of gears and rotating dials connected to the wheels, while modern digital odometers use electronic sensors to detect wheel rotations and display the distance digitally

Purpose and Importance

• It helps drivers and mechanics track mileage for maintenance schedules such as oil changes and tire replacements.
• It is essential for assessing vehicle wear and tear and estimating its remaining lifespan.
• Odometer readings are critical for determining a used car's value and resale price, as tampering with the odometer is illegal and affects vehicle valuation

In summary, the odometer measures the total distance a vehicle has traveled by counting wheel rotations and converting that to distance, providing essential information for vehicle maintenance and valuation.
