A residual fuel measuring apparatus comprising sensor means for sensing the fuel level of a fuel tank and for producing an output signal whose magnitude varies in a non-linear relationship with changes in the fuel level in said fuel tank; converting means for converting the output signal from said sensor means into a signal representing the amount of residual fuel in said tank including means for storing characteristic values representing the relationship between the non-linear output of said sensor means and the amount of residual fuel in said tank; and means for producing an indication of residual fuel on the basis of successive outputs from said sensor means during a predetermined period of time, including means for dividing the output signals from said sensor means into large values and small values during said predetermined period of time and obtaining a mean value between output signals of a given order of magnitude amongst the output signals of large value and small value received during said predetermined time period, and means for applying said mean value to said converting means.
