Different devices are used in automobiles to measure various parameters:
– Speedometer: Measures the instantaneous speed of the vehicle.
– Odometer: Measures the total distance traveled by the vehicle.
– Tachometer: Measures the engine’s rotational speed (RPM).
– Fuel gauge: Indicates the amount of fuel in the tank.

A Cathetometer is a laboratory instrument used to measure vertical distances precisely. A Lactometer is an instrument used to check the purity of milk by measuring its density.

Therefore, the device fitted in automobiles that shows the distance traveled is an odometer.

– An odometer is specifically designed to measure the distance covered by a vehicle.
– A speedometer measures speed.
– Other options are not used in automobiles for measuring distance traveled.

Modern odometers are typically digital, while older vehicles used mechanical odometers with rotating number wheels. The term “odometer” comes from the Greek words ‘hodos’ (way or path) and ‘metron’ (measure). Trip meters are usually integrated with the odometer and can be reset to measure distances for specific journeys.
