A fuel gauge for vehicles includes a memory circuit for storing a value for residual quantity of fuel contained in a fuel tank when an ignition switch is turned off and a display unit for displaying the value for residual quantity of fuel stored in the memory circuit when the ignition switch is turned on so that an indication for residual quantity of fuel contained in the tank when the ignition switch is turned off is not different from an indication for residual quantity of fuel in the tank when the ignition switch is turned on even if the tank is deformed due to change of an internal pressure in the tank. |
