Odometer
An odometer or odograph[1][2] is an instrument that shows the distance traveled by a vehicle, such as a bicycle or automobile. It can be electronic, mechanical, or a combination of the two. The name comes from the Greek words hodós ("path" or "gateway") and métron ("measure"). It is sometimes called a mileometer or milometer.
