Abstract: An adhesive label for the application of kilometer per hour speed values to a speedometer bearing miles per hour indicia bears two sequences of numerical indicia, one being speed values in miles per hour and the other being corresponding values in kilometers per hour. The front sheet of the label has an adhesive coating protected by a peelable backing sheet and is severed to permit peeling from the backing sheet of separate portions of that front sheet, each such portion bearing a kilometers-per hour value and optionally a corresponding miles per hour value so that each such portion can be applied to a speedometer cover glass in an appropriate position. Usually, the front sheet of the label is severed or perforated between the two sequences of indicia. Alternatively, the miles per hour indicia can be printed on the backing sheet so as to be visible through a transparent front sheet.
