What does tripmeter measure
Most modern cars include a trip meter (trip odometer). Unlike the odometer, a trip meter is reset at any point in a journey, making it possible to record the distance traveled in any particular journey or part of a journey.
Most trip meters will show a maximum value of 999.9. The trip meter may be used to record the distance traveled on each tank of fuel, making it very easy to accurately track the energy efficiency of the vehicle; another common use is resetting it to zero at each instruction in a sequence of driving directions, to be sure when one has arrived at the next turn.
speedometer - speedometer measures the speed at which you are traveling (how fast),
odometer Tells you how many miles the car has done since its inception or Birth.
Tripmeter It tells you how many kilometer you have driven in a particular trip.
