An '''odometer''' or '''odograph''' is an instrument used for measuring the [[distance]] traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two ([[electromechanical]]). The noun derives from [[ancient Greek]] {{lang|grc|ὁδόμετρον}}, ''hodómetron'', from {{lang|grc|ὁδός}}, ''hodós'' ("path" or "gateway") and {{lang|grc|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 of Nations|Commonwealth]].{{dubious|date= July 2017}}
