A fuel measurement system for measuring a fuel consumption amount of an engine, intended to reduce a measurement error of a Coriolis flowmeter to thereby improve measurement accuracy and reproducibility of a fuel consumption amount. The system includes: a Coriolis flowmeter provided on a fuel supply path for supplying a fuel to the engine to measure a flow rate of the fuel in the fuel supply path; and a temperature control mechanism provided in an upstream side of the Coriolis flowmeter on the fuel supply path to control a temperature of the fuel flowing into the Coriolis flowmeter.
