A smart personal portable blood pressure measuring system comprises a smart blood pressure measuring base, and a portable blood pressure measuring apparatus comprising a metal electrode detecting unit for detecting an electrocardiography (EKG) signal, a photoplethysmography detector for detecting a photoplethysmography (PPG) signal, a storage unit, a first central processor, a first power supply, and a first coupling interface unit. The storage unit stores a plurality of blood pressure values and a blood pressure algorithm. The first central processor performs a calculation according to the EKG signal, the PPG signal and the blood pressure algorithm. The first power supply provides the necessary power for operating the portable blood pressure measuring apparatus. The first coupling interface unit is coupled to the smart blood pressure measuring base so that the smart blood pressure measuring base is capable of transmitting data to the portable blood pressure measuring apparatus.
