The invention provides an electronic metering temperature and pressure compensation method for a gas meter, and relates to the technical field of pricing accounting. A counter register stores a temperature and pulse number comparison table, which is segmented in units of 10 DEG C. The number of pulses corresponding to each end-to-end temperature value is a threshold pulse number; the number of collection pulses returned by a temperature sensor and the threshold pulse number of each calculation segment are compared, a calculated temperature score is obtained, and the calculated temperature score and the temperature value corresponding to the number of small threshold pulses are added to obtain a temperature value; and by comparison with the standard temperature, pressure, and gas volume, the gas usage volume under operating conditions is obtained. According to the method, the technical problem that gas meters are used in different environments of temperature and pressure in the prior art, and the metered gas v
