Hodometer vs. Odometer

By Jaxson

  • Odometer

    An odometer or odograph

    is an instrument used for measuring the distance travelled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two. The noun derives from the Ancient Greek word ὁδόμετρον, hodómetron, from ὁδός, hodós (“path” or “gateway”) and μέτρον, métron (“measure”). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometer, the former name especially being prevalent in the United Kingdom and among members of the Commonwealth.
