1. A display apparatus for a vehicle comprising:
- display means for displaying a value of a parameter relating to an operation condition of the vehicle in a predetermined unit of measurement of the parameter which is speed of the vehicle;
sensor means for detecting the parameter and producing a first signal representing an actual value of the parameter in the predetermined unit of measurement;
storage means for storing a plurality of programs, each program enabling processing of the first signal to produce a second signal representing a displaying value of the parameter in the predetermined unit of measurement by which the parameter is displayed by said display means, said programs being previously prepared based on, respectively, predetermined different relationships between the actual value of the parameter in the predetermined unit of measurement and the displaying value of the parameter in the predetermined unit of measurement;
means for selecting one of said programs;
arithmetic means receiving the first signal for processing the first signal according to the selected one of said programs so as to produce the second signal representing the displaying value in accordance with the predetermined relationship between the actual value and the displaying value corresponding to the one selected program; and
means for applying the second signal produced by said arithmetic means to said display means for enabling display of the displaying value of the parameter in the predetermined unit of measurement.
