The invention relates to the field of gas measurement, and in particular relates to a gas consumption measuring method and system for a spaceflight gas supply system. The method comprises the following steps: calculating the consumption of gas in a gas cylinder in the spaceflight gas supply system according to at least two acquisition parameters in the spaceflight gas supply system; and calibrating sensors in the spaceflight gas supply system according to the consumption. The gas consumption is calculated through two or more acquired parameters in the spaceflight gas supply system, the consumption can be rapidly and accurately calculated in multiple channels, in addition, the sensors are calibrated through the consumption, the workload of manually checking all the sensors in the system after each time of use can be reduced, in addition, calibration is carried out through the consumption, and the judgment whether the sensor is different or not can be improved. 本发明涉及气体测量领域，尤其涉及一种航天供气系统用气量测量方法及系统。该方法包括，根据所述航天供气系
