A blood pressure measurement data processing method includes obtaining first calibration data of a user and pre-stored second calibration data of the user determining, according to the first calibration data and the second calibration data, an optimal function used to represent a function relationship between a pulse wave transmission time and a blood pressure value of the user obtaining a current pulse wave transmission time of the user and calculating a current blood pressure value of the user according to the current pulse wave transmission time and the optimal function.
