Lesson plan
Speedometer
Aston Martin speedometer's self-test routine, showing how an analogue speedometer hand may indicate the vehicle's speed speedometer, showing both mph (outer) and km/h (inner), as well as an odometer in miles speedometer in a Honda Insight A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. Other vehicles may use devices analogous to the speedometer with different means of sensing speed, eg. boats use a pit log, while aircraft use an airspeed indicator. Charles Babbage is credited with creating an early type of a speedometer, which was usually fitted to locomotives. The electric speedometer was invented by the Croat Josip Belušić in 1888 and was originally called a velocimeter.
