A Mangels, tout se passe dans le compteur. Dans ce document en anglais : http://home.comcast.net/~rhodes/speedo.pdf, il y a ce passage concernant la conversion de km en miles Pour passer de miles en km, faire l'inverse. Traduire avec Google: " KPH and MPH speedometers are essentially the same and parts exchange guidelines apply here as well. As far as I can tell, the actual speedometer function is exactly the same. Only the printing on the dial face is different. The odometers are also essentially the same. The KPH units have 62% fewer teeth on the gear mounted on with the odometer wheels so there will be more turns of the odometer for the same distance travelled. It is fairly easily to convert a KPH speedometer to an MPH unit. All you need to do is exchange the dial face and install the proper odometer gear to set the desired calibration. To convert from KPH to MPH, you can calculate the desired calibration by multiplying the calibration printed on the dial of the KPH speedometer by 1.609. The reverse calculation may be made by dividing by the same number. The resulting number usually will not correspond to an actual calibration that was available on speedometers. You need to round to the nearest 20, 25,or 32 (the number of teeth on your worm gear). For example, a common TR6 KPH speedometer has a calibration of 740. This corresponds to an MPH calibration of 1190.6. This is just about centered between the two possible calibrations of 1180 and 1200. To settle the issue of the what calibration you REALLY should have, you ought to calculate your ideal calibration as described later in this manual, then translate that into a MPH/KPH calibration and then look for the best possible calibration available " Jean
