PURPOSE: A fuel injection amount measuring device for a running vehicle is provided to easily obtain a fuel ratio of a certain section in proportion to a fuel injection period which controls an injector by an ECU by simply setting a logic to sense a fuel injection period and an increase/decrease ratio of a vehicle speed. CONSTITUTION: A fuel injection amount measuring device for a running vehicle includes an electronic control unit(ECU) for comparing a vehicle speed, a testing set value obtained from a fuel injection period(ms) until a predetermined fuel amount is injected from an injector, and a measured value of a fuel consumed via a fuel injection period(MS) that an injector mounted in a vehicle applies a fuel injection, an A/D converter for converting an analogue signal with respect to a fuel ratio computed in the ECU to a digital signal, and a fuel ratio displaying element for displaying a fuel ratio according to the digital signal.
